Buddy of mine fell off his nitro Harley at 180 while his wife was taping the run. He had a brand new racing suit on that didn't have doubled knees with cup inserts. Bad timing. His knees took a beating but the tumbling broke several fingers. Watching the video, its amazing Rocky lived through the crash.
Needless to say, when he wanted to get back into racing, his wife put her foot down.
PS: I got the last of his nitro methane drum. A little bit sure makes a motor run good!
