Skiing is classed as a dangerous or extreme sport with the insurance agencies, and thankfully I've never had anything worse than a twisted ankle or a few scraps from going through a tree line or two. So I'm wondering what's the worst thing you've seen (or caused).
I remember when I was in Solden once, when I was learning to ski, I crashed into this cute girl who really annoyed and serious after I ploughed into her and ended up getting tangled. But nothing was hurt, well I wasn't anyway

I've also seen people being airlifted off the piste once. There was a bump in the slope, where it crossed a road and someone lost control going over the bump and it looked liked they had messed up their legs. The rescue team had come and covered him with a blanket when I passed, and when I got to the bottom of the slope I saw the helicopter come in and land.
