I almost got annihilated by some girl who fell like that once. She went right by me going like mach 230912743, hit a bump and exploded, skis and whatever flew everywhere. I actually would have been hurt if she hit me, I bet.
Last time I went, I saw a snowboarder bomb this decently steep run. He had to turn at the bottom, and he was in it pretty good. But then he hooked an edge or something on his heelside and high sided, then rolled a few times until he stopped. It was a pretty dramatic fall, but he was fine.
Also, if anybody saw my post about the asian family in line in front of me. Later, the asian kid was on the ground, he's a snowboarder. And his dad is yelling at him to GO BACKWARDS in his heavy chinese accent. That was the running joke for the rest of the day.
