Well, my bike finally let me down. For the first time since I've been commuting by bike, I had a failure that I couldn't fix on the road. I broke a spoke on my front wheel and it just wasn't ridable. Fortunately, my parents were in town and my Dad was kind enough to swing out with a car and rescue me, otherwise it would have been a walk to catch the bus. This is the first spoke I've ever broken on a road bike, all the rest have been off-road, resulting from very obvious causes.
