Well, actually now that I've read Mine turtle's and Statyk's experiences that involved skiing/snowboarding I remember one thing that happened when I was about 9-10 years old. This'll be quite hard to explain so bear with me. I was skiing with my dad and aunt in a pretty easy slope and I hurt my foot. I was pretty sensitive and would cry a lot back then and it wasn't a big deal, so my dad and aunt kept on going. I sat down at the side of of the slope. Before the slope there was a flat part so the slope kind of looked like this:
Well, I sat there and rested for a bit, while my dad and aunt kept going down the slope and I couldn't see them anymore. I had been there for a couple of minutes when all of a sudden a snowmobile drives right behind me, pretty fast:
I looked behind me and saw the front of it right over me. The driver managed to see me in time and steer to the right. He asked me why I sat there and I told him that my foot hurt, he gave me a ride down the slope yaddayadda. Well, if he hadn't have seen me I would've been crushed by a 500 lbs and probably not be here right now.
