Bike day

I bike to work 3 or so days/week.  But today was more “bike stuff” than usual.

In the morning I went to the Atlanta Bicycle Coalition breakfast, held at Atlanta Beltline Bicycles.  It was to kick off Bike to Work Month.  Great food, and I met a few fellow Georgia Tech faculty members to create a team for the monthly bike-to-work events (we are team “Fuzzy Bees”).  While there, I checked out the bikes.  I had been to their shop when they were located in Avondale Estates.  Since moving to the beltline, they have a much bigger shop and a GREAT selection of used bikes.  Biked 55 minutes biking to the breakfast and then biking to work.

I worked late and left campus around 7PM.  I decided on something a bit risky – biking down Ponce de Leon Ave.  I don’t normally bike on city street where the cars like to drive sometimes faster than 40 mph on a crowded street. The road has been restriped with the intent of a bike lane — in fact, all is there except the bike lane stripe – there is plenty of room for cars to pass.  I biked Ponce from Peachtree to Murder Kroger – it was awesome!  It lowered my commute time – a lot – vs winding around neighborhood streets. This will have a big impact on bicycle commuting when the bicycle lanes are finally painted.

It occurred to me while biking down Ponce that bicycling in Atlanta has some similar feelings of joy and frustration as driving/riding a car in country with developing infrastructure, like India or China.  There are brief episodes of speed and progress, punctuated by lots of wandering awkwardly around side streets along the way to your destination.  My daily bicycle commute is certainly that way.

Atlanta infrastructure for bicycles is developing fast.  I had not ridden the Beltline trail south of the Freedom Parkway trail before.  Like the the rest of the East Beltline, development along the trail is evident everywhere. Businesses and real-estate developers see what a catalyst these trails can be for urban neighborhoods.

Where are we going with this? Many have fought for bicycles to have equal access to roads.  This was a good idea when we were starting from nothing.  But I think we need to rethink this share the road bike==car approach.  Bikes are different.  Bikes are not cars.  They are not pedestrians.  Just as cars and pedestrians have different “modes of operation” so do bicycles.  I am legally supposed to ride on the road, but in some places it is crazy to do so.  Or cars yell at you.  At the same time, the sidewalks in other places are poorly maintained, or crowded, or unsafe for a bike to pass a mom pushing a kid in a stroller.  Our infrastructure is starting to reflect the unique aspects of bicycling as a mode of transportation.   I hope in the future we finally realize that bicycles need distinct traffic laws from cars or pedestrians, and stop trying to pretend they should behave like one of the other.  I am not asking for special privileges, just a legal framework that reflects how a bicycle is safely operated and interacts with traffic.  It may not mean special lanes, but a different way of considering intersection design, or stop lights.  I hope that these discussions will eventually lead to changes that reduce car/bicycle conflicts, which seem to me to be on the rise as more people in Atlanta take to the streets on their bicycles.

Bike Trunk

I have had a few questions around campus and on the road about my “bike trunk.” So here are a few photos and a brief description.

Why? I’ve had one of those soft side trunks that straps to a bike rack. Most of it is general necessities for biking – lights, tube, repair stuff, bungee, spare glasses. I HATE having to take it on and off the bike every time I stop somewhere.  They are not designed for quick release.  And since I work on a college campus, anything on a bike is a potential theft item.  So I sought to craft something permanent and lockable on my bike rack.

I settled on a 30 cal ammo box.  A wider box would be nicer, but the 30 cal is narrown enough on the rack that I can still mount my panniers on the rack when I need to use them.  The box is mounted to the rack with 4 1/4-20 bolts, lock washers inside and rubber lined washers (for grab) on the outside. Inside the box the bottom is 1/2″ of minicell foam and I glued thin foam (shelf liner) to the sides to minimize rattling.  The lock is simply an adjustable shackle lock through two holes that I glued.  Finally,  I added two u-bolts to the side to make it easier to carry my 12″ long bicycle lock.

The Road Less Traveled … Spring 2011

We are doing a multi-week camping trip out west in Evie, our VW poptop van.  I’m not blogging about the trip because Gwyneth does plenty of that on a daily basis on her blog.

However, I’m writing this post to log some of the “definitely worth a visit” places we have been to that are not as famous as, say, the Grand Canyon or Yosemite.  I’ll update this as the trip progresses.

  • Best scenery while driving: back roads around Four Corners in the area of Valley of the Gods and Monument Valley.  Amazing view of red and colorful sandstone mesas and rock formations for over an hour of driving.  It is kind of like the inverse of the Grand Canyon.  Some of the drive is also along the San Juan River, which drains some of the mountains of SW Colorado into Lake Powell from the east.  How: From US 160 in Colorado NW of Four Corners, travel Utah and Arizona state roads through the towns of Aneth, Montezuma Creek, Bluff, Mexican Hat, Kayenta.  In Bluff, stop at Navajo Pizza at Twin Rocks Cafe.  Gwyneth has some photos of the drive posted here.
  • Mesa Verde National Park.  This park rocks!  I would love to return for several days of day hikes or an extended overnight hike.  Ample camping that supposedly never fills up.  Amazing elevated canyons that are lush and green, combined with amazing cliff dwellings (much more impressive than Gila).  Some look like small cities.  Gwyneth describes our day there here.
  • Mt. Diablo State Park.  This is a California State park just east of the Bay Area near Danville, CA.  The highest campground, Juniper, is at over 3000 feet.  The peak of Mt. Diablo is supposedly the #2 spot in the world for the amount of land area visible from the peak (a feature of its relative height vs. the surrounding area).  Here is an amazing shot taken our campsite taken when I woke up – we were above the cloud cover!
  • Capitol Reef National Park. Bryce and Zion get all the attention, but this nearby Utah park is worth the drive – the Capitol Gorge drive, that is.  You can drive the wash of a narrow gorge (assuming no rain that is!) for a fascinating bottom up view.
  • Goblin Valley State Park. Possibly the coolest place we have camped.  This Utah State Park is full of mushroom-like rock formations called “goblins.”  The campsite is surrounded by soft sandstone cliffs that are fun for climbing and scrambling.
  • More great scenery while driving: …

Kayaking is risky … but not necessarily on the river!

Day 2 of solo cabin weekend.  I had decided to paddle the Toccoa, a local class II creek.  It is normally a sleepy trout stream and summer tubing run, but after a good rain it can be a lot of fun. I also only paddle it in the winter when the lake level is low, since the lowered lake level uncovers a bunch of atypical sloping ledges that are normally at the bottom of the lake when it is at full pool in the summer.  It was still pumping after all the rain Wednesday (large basin!) at 700+ cfs, several times the usual levels.  It was fun!  Lots of surfing, and I helped teach a new kayaker who lives up in Blue Ridge.

The takeout is a rough dirt road that leads to the lake, which is a lake bed this time of year.  I would only drive that road with an AWD car, which of course my Subaru is 🙂

The day was fun and without incident.  We got to our cars and were loading our boats to go home.  I was the last to leave, taking my time and enjoying the view and weather.  As I backed my car up near the lake bed, all of a sudden I lost traction.  How?  I have AWD?  Nothing can stop me!  Yet, all my tires were spinning.

I got out of the car and saw this:

Stuck car

AWD doesn’t help when there isn’t much weight on the tires!

I suppose this is why off-road 4WD trucks have high clearance 🙂 I also suppose they have a name for this situation. After 5 minutes of trying turning the wheels, forward, reverse, etc. it was clear I was doing nothing but spinning all four tires. I tried banging some rocks under the front tires for traction but that didn’t help. I tried calling my friends but the cell phone coverage barely works. So I stopped and did some thinking …

The wheels were turning, which means some weight was on them (AWD redirects power to the wheels with traction). But clearly a lot of the car’s weight was being supported by the ground in the middle. I decided to get out the car jack and lift the front left side of the car. My thinking was that it would shift more weight to the rear tires if I got the jack high enough, and would also result in more power being distributed to the rear tires since the front would have no traction at all once lifted. Yes it is a little dicey to try to move a car with a jack under it, but the car was only lifted a few inches and I had a hunch the jack would tilt back, not fall, given how deep it was squished into the ground. Nervous, I started the car, put it in reverse slowly, and the car moved! Not enough – but the car did move back about one foot.  It was again stuck in a similar manner. Encouraged by the positive results, I spent 10 more minutes trying again – move jack, raise jack, put car in reverse and … I was free!

Bumper cover damage

Bumper cover damage 🙁

But I also had some body damage. Reversing down the drop dislodged a bunch of screws/rivets holding part of my front bumper cover in place.   I didn’t notice it at first until I saw a piece of plastic on the ground and wondered where it came from.

Duct tape fixes everything

Duct tape fixes everything.

I suspect I can fix this without going to a body shop – it needs some new reattachment – it is definitely not worth an entirely new bumper cover, paint, etc.  But in the interim, there is always duct tape, which is in my first-aid/rescue/emergency kit that I take kayaking.  It is not pretty, but it works.  100 miles later, 3 of the pieces were still holding strong!

Is there a lesson here?  Look before you leap?  This could have been avoided if I had remembered exactly what the nearby gradient looked like.  Drive an AWD? If this car had been front wheel drive, I would have had to call a tow truck.  On the other hand, if this car was not AWD, I may not have driven it where I was!

Maintaining the land in the mountains …

A tree fell at the in-law’s cabin a few weeks ago.  Thankfully, it missed the house (though it was close).   A great neighbor came by with his chain saw last month and got a good start – he cut all the branches and cut the trunk into 8-12 foot pieces for about the top half, as in the picture below.

Tree After Mike

Fallen (pine) tree. Neighbor had cut all the branches off and made some efforts at cutting up the trunk.

I was hosting an out-of-town visitor who stayed at our house Friday night, and the family is out of town. So Saturday morning, after dropping him off at the airport, I headed up to the cabin with chainsaw, tree climbing gear (for fun afterwards), and kayak (for fun Sunday).

I started by hauling away all of the branches that the neighbor had cut. His cutting all the branches was a great time saver, and it only took me less than an hour to get them all dragged away to piles in the woods. The it was chainsaw time. The lower 30 feet or so of the truck had not been cut, and the upper trunk was cut into 8-12 foot pieces. They are quite heavy, so I needed to cut them even smaller. Don’t worry mom – I never lifted anything. All trunk logs were rolled.

Surprisingly, the chainsaw, which I had not used in probably 5 years, started right up! Even with the old gas in it (I usually put a gas preservative in, but still …) After about an hour of cutting, I started dragging and rolling. I then returned to the saw to cut some saplings that the tree had fallen on. After that was done, I thought I was finished, when I decided to cut another sapling that was growing out of the base of the tree and was now “sideways” from the tree’s root ball. At this point, the pull cord of the chain saw got caught/locked. The tools I needed to fix it are not here, and I was pretty much done anyway, so I think it is karma’s way of saying “good enough!”

Yard after Rob had removed the fallen tree.

The rest of the day consisted of visiting the lake to scout the take-out for tomorrow’s kayak trip, visiting town to buy a bucket for a possible sump project at the cabin, and dinner (burgers and italian sausage on the grill).

One day after cutting, the exposed stumps all have a ring of pine sap on the outer two inches or so.

Mote Marine Aquarium

With Camile sick, Chloe and I headed to the Mote Marine Laboratory and Aquarium in Sarasota.  I love this place — it is a research facility and rehab hospital for injured dolphins and whales.  So while smaller than other aquariums, it has a strong science component and is very hands on.  Highlights include the resident manatees Hugh and Buffett, the dolphin pool (contents may vary based on what the hospital is doing), and sea turtles.  Plus some great aquariums as well.

I saw Jupiter!

For Christmas I got “the kids” a telescope.  This was largely motivated by our home schooling, since the kids both have an astronomy component.  But it was equally motivated by my desire to learn my way around the night sky.

I never understood astronomy.  What’s so cool about looking up?  One of my fraternity brothers in college was so “into it” he would road trip to remote spots (like Alabama) far from light pollution to look at the stars.  Maybe it is this lingering memory that had me thinking it might really be interesting (thanks Paul!)

I agonized over what to purchase, and how much to spend.  After way too much web surfing, I decided to get a decent but low-end refractor telescope.  I was tempted to spend more and buy a 6″ Dobsonian, but decided on something “good enough” to see some interesting stuff and make me (and the kids) decide if we want something more.  I purchased this model from Orion, both for it’s price point ($99), the table top mount (easy for the kids), and the fact that the bottom had a tripod mount that enables me to use Gwyneth’s hefty Bogen tripod.  This is an 80mm scope with a 350mm focal length, and comes with 10mm and 20mm lenses.  This results in magnifications of 17.5x and 35x.  I also purchased a Barlow lens (changes the focal distance of the eyepiece and allows a 2x magnification).

To learn my way around the night sky, I also purchased the book Nightwatch.  This book is excellent.  It starts using easy to recognize stars and constellations (Big Dipper and Orion), and has a different initial sky walkthrough depending on what season (and what hemisphere) you are in.

I was hoping that a brief trip to Florida this week would provide the clear sky needed for learning my way around. Our trip yesterday to Kennedy Space Center provided added motivation. Two hours later, I am utterly awed.

The writer of the aforementioned book emphasizes learning your way around the night sky with a decent pair of binoculars.  My parents have a a nice pair of 10×56 Nikons – decent magnification and a wide field of view.  I was amazed what you can see with the binoculars!  The Pleiades star cluster, barely visible with the naked eye, is just mind boggling with the binoculars.  Even my father was wowed when I showed him where to look with the binoculars.  The Orion nebula (M42) is also able to be made out.  After learning a few key stars (Betelgeuese, Bellatrix, Aldebaran, Rigel, Sirius) I decided to try out the scope.

The field of view is definitely different with the scope.  The 17x images were not too different than the binoculars, but obviously steadier with the help of the tripod.  I wish the focus had a remote control – just like using the microscope at work, the act of even touching the focus perturbs the image.

I then set my sights on what I assumed to be Jupiter.  Wow.  Even at 17x, the fact that it was a larger disk than anything else made it clear that I was looking at a planet.  At 70X (20mm eyepiece and 2x Barlow) I could actually see features.  Once my eyes adapted, it was possible to see the faint bands of clouds that run across the planet.  As well as what I think were 4 of the moons.  Due to the narrow field of view, it was necessary to nudge the scope every minute or so to track.  I decided against an equatorial mount (has an axis of motion that moves the scope to compensate for the earth rotating) since I did not want a complex thing to deal with, but I see the attraction.

I’m now hooked on the night sky.  A pair of binoculars, if not the telescope, will be a must on any camping trip to North Georgia, where the night sky is amazing and far from major sources of light pollution.  In fact, I’d like to buy a decent pair with a tripod mount.

Seeing Jupiter, the Orion Nebula, Pleiades, and several stars via both the scope at different magnifications and just using the binoculars has given me an amazing appreciation of “how much” is really up there that our eyes cannot even make out!

Now I need to go back out, since it is about time to try to spot a satellite flying by 🙂

The coming end of the optical disk?

I have been wondering for years when this would start.

USB “drives” have become ubiquitous.  8 Gb models now retail as cheap as $10, and cost much less than that to produce.  Read-only (ROM) style memory requires even fewer transistors, and I would guess would cost an order of magnitude less to produce.   I am guessing that a read-only USB drive would likely cost tens of cents to produce.

So when will they replace optical discs?  A DVD is 7.4 Gb.  They are prone to scratching.  I have had 2 Apples that have never liked DVDs too well (out of the 5 Apples that I have had at work or home).

Macbook Software Reinstall Drive

Mac Software Reinstall Drive (photo from engadget.com)

Today I saw the first sign.  Gwyneth recently had her Macbook Air replaced for free even though it was out of warranty (yeah Apple, great customer service, even if that computer was a lemon).  Tonight I was filing the paperwork and DVDs.  But there were no DVDs!  Instead, there was a USB drive inside the package – labeled “Software Reinstall Drive.”  Cool.

I wonder when these will become mainstream.  The data rates of USB 2.0 (up to 480 Mbps) can handle the typical data rates for playing a DVD (3-10 Mbps), though there are other reasons (cost of production, digital rights management/copy protection) why we may not see USB-drive “DVD’s” anytime soon.  But it is a great idea to think about.  Besides, just like Nintendo DS games, people will be more likely to lose them and need to buy replacements!

Yes, BluRay has 10 times the capacity, but I think my arguments here still apply, you just have to look a little further out.

Visiting Mary Alice

Ropes set in Mary Alice

Ropes set in Mary Alice

An off-hand comment on a whitewater email list a few weeks ago started a conversation of “do you tree climb?”  It resulted in an invitation for Chloe and I to visit Mary Alice, a willow oak maintained and groomed for tree climbing at Lake Hearn in Fayetteville, Georgia.  I was invited by Mike Ivie, who currently runs the grove and offers a public climb twice a month on Sundays.  We drove down and were met by Mike and Abe Winters, a long-time tree climber and instructor who founded the grove.

The setting is beautiful – a well maintained grove along a path by the lake.  In addition to Mary Alice, there is a smaller adjacent oak with much lower branches – ideal for kids with fear of certain heights who still want to get into the branches.  We will try that one on our next visit.

Given that Mary Alice is a well groomed tree, there are no sucker shoots or nearby trees in the way which means — no tangles!  My throw line was set in 2 throws, and the subsequent attempt to set a line for Chloe’s rope hit the first time.  I’m usually not that lucky good.

While Chloe helped Mike lay out gloves and equipment for visitors for the public climb, I ascended about 30+ feet until Chloe came and wanted to climb.  Chloe alternated her time climbing and swinging.  At one point she hit her height limit of 20′ or so and got scared, but we lowered her down and she was happy again.  So happy, that she ultimately decided that rather than climb, she wanted to spend her time in an upside down “bat hang”, swinging to and fro about 30 feet while about 8 feet off the ground!

Mike and Abe were great hosts, and we will certainly be back.  Chloe kept my occupied, and I really didn’t get to explore the heights of the tree, which looks like I could spend hours in. I learned a lot talking and watching both Mike and Abe. They each do certain “climbing things” differently from each other.    Just like in kayaking, different instructors provide different perspectives on technique.

Hiking and Climbing Free Knob

novel river craft?

I have not done any “wilderness” climbs – hiking in the woods just looking for a tree to climb.  I have always wanted to climb to the top of Free Knob.  Free Knob is a local peak located near the Toccoa River in Blue Ridge, Georgia. In fact, over 8 miles of river winds around Free Knob, and it is possible to kayak from Sandy Bottom to Tilly Bend and walk about a mile back to Sandy Bottom. (Note for boaters: Persimmon Creek downstream is a much easier takeout!)

I drove to Shallowford Bridge Road from the family’s cabin located nearby.  On the way, I spotted an “intersting” watercraft (see photo).  The hike up to Free Knob from Shallowford Bridge Road is only one mile long, but it is over 500 feet in ascent.  I veered off the Benton MacKaye trail and bushwacked up the slope.  Carrying my pack of climbing gear, the final ascent was quite steep!

The top of Free Knob was interesting.  Some of the oldest and largest trees I had seen were at the top, which surprised me.  Looking past all the trees, the 360 degree view of the surrounding area was incredible.  I had hoped to find a tree to climb to see above the canopy, but fate and my climbing skills didn’t get me that high.

A rather ideal oak looked great to climb, but it had too many sucker shoots and my target for a rope crotch was at the height limit of my throwing accuracy.  I gave up and chose another nearby tree that I expected to have a throw line into right away.  I was wrong. While the tree looked easy to target, the surrounding trees kept on snagging the line going up or coming down in inopportune ways.  I finally did manage and got a line up about 40 feet.

180+ degree view from a tree atop Free Knob looking east

The view was awesome – I could actually see both Tilly Bend (well, a lake house that I recognized was at Tilly Bend) as well as Sandy Bottom from my vantage point.  I was unable to throw to an ideal location to set a second pitch, so I eventually gave up and came back down.  I named the tree “Free At Last” due to its location and my feeling that I’d never stop trying to get a throw line into the tree.

I then climbed a second tree located a few feet down the slope, thinking it would have a better view looking east.  I was right.  The panorama in this posting is a composite of 6 photos that I took spanning about 180 degrees of view looking approximately east.  This photo was taken while I was standing on a branch about 25 feet off the ground for stability. I named this tree “90% Discount” since I got the throw line about 45 feet up on only my second throw, and the climb was quick and uneventful.

The hike down was uneventful.  I spotted some odd looking trees, and while making lots of noise bushwacking back to the trail encountered a hunter, wearing his camos with an orange vest.  It IS hunting season, and maybe I should wear my orange vest the next time I go bushwacking off a trail in a National Forest.
