I was in a hit-and-run a couple of months ago. I got a nasty abrasion plus a couple extra cuts on one leg and the heel of one palm was very sore. The bike was rideable. After giving the report to the police I rode home figuring it wasn't as bad as half the crashes I've seen in the Tour de France. I've ridden every day since and went out a week after the crash to finish the ride I was on.
Now the one time I haven't gone back to finish a 2-wheeled ride was when I crashed out of the 2006 Baja 1000 and broke some ribs. I'd have to go over 2000 miles from Minneapolis just to get to where it happened!
