Probably the worst injury I have had was when I was trying to ride a box in the park next to my lift and went head first into the ground(note to self, should get a helmet before doing boxes), that hurt for a bit... but I was mostly ok. Well that or when i went down some moguls in deep powder(like a foot or more) on a ski break, in full aspen uniform, and right infront of some guests when I caught an edge, lost my ballance, and went head first into a crazy upside down what-the-hell is happening spin throwing a huge cloud of snow. didnt hurt a bit, just felt stupid. Popped right back up to there questions of "are you ok?" lol...I'm supposed to be riding carefully on my breaks! But that powder was awesome, especially once I set the board up for it. Its still out there too, its fantastic.
