LtCthulhu

Its about a boy who is flying somewhere, I think to visit his parents or something in Canada, and the pilot of the small prop-plane has a heart attack while in the air. The plane crashes in a lake and the boy is forced to survive in the Canadian wilderness. It's a great book. Mostly geared towards kids I think, but can be enjoyed by any age group.

Were you close enough to yell to the people nearby?

I just had a mild daytime nightmare of a branch crushing me but not killing me, and then not being able move to get the walkie.
