I haven’t written much to the blog lately, and I attribute that largely to the holidays. I like the holidays, and they play an important role in my life and the lives of my loved ones. So, I was busy. This is the first weekend I’ve been home in a while.

And, thanks to xmas, I’ve got a bunch of new presents! My family and friends are very generous around xmas. In fact, I am struck by how often when someone asks where I acquired something I own, I say it was a gift. Really, a surprising percentage of the durable goods that I own were gifts. Of course, I try to be generous as well, and so does everyone, so perhaps the same is true of most everyone I’m close to. But I think my aversion to shopping in general probably raises the percentage for me.

Anyway, I think I was particularly easy to shop for this year because of my increasing interest in cycling. So, I had a new:

  • handlebar bag;
  • frame bag;
  • bike gloves;
  • long underwear;
  • (unbelievably cool) repair tool;
  • (and the biggest gift of all) GPS

Well, much to my surprise, the weather was very nice this weekend. Actually, I’ve loved the weather so far this winter… seems like it’s either snowing or clear. Clear, cold, and sunny doesn’t bother me at all, although I admit that cold does not make me excited about long bike rides. But still, what I don’t like (and what we typically get a lot of in the winter) is cold, overcast, and drizzling. Yuck.

Anyway, yesterday was very sunny, and I thought “I could bike in this.” Then, today, it was not only sunny, but even quite warm! It topped 60 this afternoon! Woah!

Well, how could I resist? I installed my new handlebar bag (with my new unbelievably cool repair tool), figured out a way to attach my GPS to it, strapped on the frame bag, donned the gloves and the long underwear, and set off! I rode a variation on one of the easiest routes that I do, one of my “12 mile after work” routes that can be ridden in about an hour. Usually I do these routes for the exercise and the mind-cleanse, so I usually push myself a bit. Today, though, I was telling myself to “play”. Every time I thought of something I might adjust or check with my new gear, I tried to check it. So, definitely a slower ride than usual. And then I went out of my way to go to Staples to buy me a new Flash/USB drive (I should write about that in a different post).

The ride went well, it did feel relaxing. But, part of my excitement to bike was to unveil the new abilities made available to me by the GPS, and some very cool software. So, now, thanks mostly to GPSVisualizer.com here is
a google map version of where I biked today and [an elevation profile](http://www.bloomington.in.us/~drernst/gmaps/20060108-surprise-ride-elevation.png) as well! I found the software and stuff necessary to do this yesterday, and I’ve been very excited about the ability. Very cool.

Furthermore, I’ve been having good luck with finding perl modules and the like to play with the GPS data myself. I was hoping I’d do a total ascent graph to post up here as well. Unfortunately, though, the data is.. not reliable. I have to learn more about some of the stuff that the GPS does with elevation, because it seems to make these corrections, often when I’m standing still. I calculated the total ascent to be about twice what the GPS said it was. I tried to correct for the corrections, but I never got it to within 20% of what the GPS said. And I’m not sure I trust what the GPS said anyway (it said ~1700 feet for this ride, that seems a bit high to me. One of my estimates came back closer to 1400 feet, but I don’t know whether to believe that or not). I wonder if part of the confusion was that it was very windy today, and that maybe the variable pressure confused the GPS’s internal barometer. Weird, I don’t know, I’ll have to research it and/or get used to it.

I could say tons about the bike ride, but I’m trying to get to bed, so I’ll just highlight a couple of things:

* Why did I ever bike up the hill on Old 37 between Dunn and Bethel? I can bike up the same hill on much more pleasant back roads. Doesn’t make the hill any easier to climb, but at least you’re not also worried about cars.
* Both of the climbs I did near Griffy were about 250 ft vertical. So that’s: from the bottom of the dam (~600 ft) to around the corner of Bethel and Hinkle (~840 ft); and from the causeway at Griffy (~650 ft (50 feet higher than the bottom of the dam!)) to the crest of the hill near the corner of Jordan and 17th St. (914 ft! I had no idea there was such a high point over there near the frats!)

Ok, enough geeky reminiscing. I’m going to bed.
