Balls O Steel? Insane? Not in my book! Dumb ass negligence, a bit more probable. Awesome adrenaline rush, yes. But dayum has my views ever changed. The wife heard the video, and came and looked over my shoulder and watched the remainder of it. She could tell I was enjoying it, she commented on how I used to ride my bike when I was in High School, and absolutely I took some very "movie worthy" dives. I'm just plain lucky I'm still here...my last go at "stardom", I was on the back wheel, shifting into third, when a car pulled out of a right side alley, I couldn't brake or steer, the first thing that hit was my headers, I "T" boned it on my back wheel, and yes I went flying, try to explain that one to the officer, LOL.
Those rushes are better kept for the track, controlled environment, and Hell! you could likely end up with a living, doing what you (think) you're good at.
