When I was a kid I always hated the fact that going sledding meant I had to spend 5 times as long walking up a hill as it took to ride down it. There's no way I would walk all the way up a mountain just to ski back down it haha. The only thing that could possibly make falling down a rocky mountain worse, is how much work you had to put into getting to the top. I'll stick to the places with ski lifts.
Side note: aren't those skis supposed to fall off when you start rolling down a hill?? He's lucky the skis didn't break his legs, if the rocks didn't.
