When I was about 11 or so, I went sledding one winter when we had an usually good freeze. But I didn't own a sled, so my dad had fashioned one out of a piece of scrap roofing metal. Anyway, after hurtling down the hill, I realized that I was pointed straight at a rather deep ditch, and there was a fallen tree crumpled in it with rather sharp pieces of wood pointed in every direction.

And being on a rather uncontrollable piece of metal, I realized I had two options: jump off, or sit there and do nothing like an idiot. I did the latter, and luckily stopped about six inches from the ditch. I imagine I would do the same thing in this situation. Well, I might try to steer whatever I was in, but I'd probably end up flipping it and faceplanting.
