did u clip ur ski on the start of the rail?..
i did that on our flat-up-flat, my ski fell off.. slide the first flat on 1 ski and 1 boot then hit the kink and sacked myself! i cried=)
Can't really see it too well, but he cased it pretty good. Slid into the up part (its an up flat down) but his front ski just stopped dead, and so he got thrown forward. I think it cracked his edge, oops!
