Years ago 5 of us were on a fast section of dirt road and my one friend went way too wide and collided with a guy coming the other way. Both went down pretty hard and the other guy got up and he was pissed, justifiably so. He was a big, muscular dude and he probably would have fought my friend except there were 5 of us.
The crash bent the down tube on my friend's steel bike so he sold it to me for $100. Good deal because it was all XT with good wheels. I bought a small frame used from my lbs for $50 and built it up for my then wife.
