This looks like fun but definite Darwin Award Candidate material

Reminds me of my son, who was 18 at the time, when he and his buddy decided it was a good idea to use a car hood as a sled, on a gravel road with about 3" of fresh snow, pulled behind a truck.
Long story short, the sled swung over to the side of the road, and my son broke off a 4X4 mailbox post with his leg.
Didn't break the leg but sure bruised it up big time.
He's 52 now, and still paying for that little stunt with problems in that leg.
 
Oh, to be young again. That certainly does look fun....until it wasn't! :)
 
Damn, I really need to make UI3's video player completely awful, using only a postage stamp sized section of the screen unless on mobile, and take away all the controls except play/pause. Then everyone will love it as much as instagram!
