Similar to the Schwinns above I got a Raleigh "Chopper" when I was in elementary school. I thought I was the king of the block
I wasn't very bright or coordinated as a kid, well...ever, and rode that bike over a large dirt jump that neighbor kids built. Now bear in mind I never attempted a jump before and had no clue what I was doing. The other kids made it look so easy. I don't remember what happened, I woke up in our kitchen as my Dad was washing the blood and dirt from my head in the kitchen sink. My friend said it was the worst endo he ever saw.
