One of the worst for me:
It wsa preseason, and there were no jumps in the park (in fact, only a tiny part of the park was open, about 50 yards long). there was one big, steep pile of snow that you could get a little bit of air off, but it was incredibly icy. the snow was slushy elsewhere, so I decided to go to the black diamond where there were 2 rollers you could get a decent amount of air off of, but you had to go pretty fast. I landed 5 in a row and on the last roller of my 3rd run, i got about 90 degrees around then caught me skis. i hit my head a couple of times on the ground and got a bloody nose. I was kinda dazed and had a headache, but I was okay after like 45 minutes. I'm lucky this is about the worst I've been in.
sparknotes: Landed some 3s off sketchy rollers where you had to bomb, caught an edge and hit my head a after I landed 5 in a row.
