Skin grafts are no fun, but once you've had them all else seems like just a papercut.

Riding is fun, always respect the bike. Always watch what others are doing and be prepared for the worst. Watching your shirtless buddy in shorts take an offramp at 60+ is insane and when he lays it down and comes out of his shoes and his ankles hit the guard rail and cut off his feet, it gives you a little more of that feeling. Just use common sense when riding.
