I was sitting near the end of a run with a long flat section to get back to the lift so you need to carry as much speed as possible.Saw a kid come around the corner on to the last steep bit before the run out flatbasing it as fast as he could. Just as the slope started to mellow his board pivoted and he did a scorpion at about 30 mph. Stopped him dead and he was out cold. When I unstrapped to go see if he was ok his buddies arrived at the same time and I saw they were the group on the chair ahead of me burning massive bowls on the way up. He blew his face up pretty good. Guy sure paid for his momentary lapse in attention.
