Once this year (my only year since I was teenager). I moved over (a little too far) to avoid some oncoming bikes on the Rail-to-trail and clipped my handlebar in a chain link fence. It mostly hurt my pride. But, I'm glad it happened -- I was feeling like an indestructible teenager and that brought me back to reality. I've slowed down a little and got a little more cautious since.

I felt a little better a couple weeks ago after I watched a video of Lance crashing for about the same reason (but he clipped a spectator rather than a fence).
