Well, I've been commuting for exactly one week, and it was great until this morning; now the bike's in the shop. While heading in before dawn this morning, I got to one section of road where a parking area for a small business kind of melts right into the road (no shoulder, curb, etc.). I had not realized that I was drifting a bit to the right. Where the parking area gets to the road, there's this one small area that has some shattered asphalt, and of course I slid in it and went down. I didn't even go down very hard, and partially caught myself. It wasn't nearly as spectacular as a crash this past winter, when I went down on some ice and slid 30 feet or so. It was, however, just right to bend my rear derailleur (or perhaps the hanger; I really have not developed any great bike-mechanical knowledge yet). It still worked, but all of my rear gears were off by 1 sprocket, and I couldn't downshift all the way or the derailleur got way too close to the spokes. The LBS was a bit backed up with work, given the time of year, and I'm hoping to be back in the saddle next week. O well.
