Its kinda lame. It was an icy/windy day and I had been sliding this wide flat box all day. The box had a sketchy lip to get on it, and like a 5 foot drop off at the end. I came up from the side, started sliding it, front ski slipped, and I fell off the end of the box and the back of my head slammed onto the hardpack. My friends had to help me walk to the ski patrol office, then they had me take an ambulance to mammoth hospital.
