worst bike wreck you have ever had?

me,my brother, and my neighbor were riding our bikes in the woods. we arrived by a hill with lots of bumps, they had real mountain bikes and got down it easily but i had a crappy little bike and halfway down the chain broke (this is bad because i had one of the bikes where you pedal backwards to stop) and i went wildly out of control. i went straight into a gruop of trees and managed to miss a few but after about 3 seconds i ran smack dab into a tree and broke my nose and almost broke my jaw. (see more)
