Sometimes gravity has a way of reminding you that what goes up, must come down. This poor snowmobiler had a bad run in with gravity,  so much so its like Sir Isaac Newton screamed from the heavens, "I TOLD YOU SO!"

This poor guy, just sliding down the mountain, with a 500 pound machine following right behind him. The thing that I was thinking while watching this video is, "how on earth is he not yelling or cursing? I know I would be."  If that fall had been planned and had he been in control more, it might have been a fun ride and by planned I mean, down the hill on a sled, not his tuckus.
