I had it my mind that you rode motocross. Those flat trackers are something to watch, and the drag bikes are damn scary. Cuz Lyle rode motocross to but that was before I knew him, I do know that he did have a bad wreck in Baja Mexico riding that damn near ended him.
I had a friend growing up that raced motocross and he was recovering from a shoulder injury and he wanted to race so bad that he got his dad to tape his hand to the handle bars so he wouldn't lose his grip.
