ironraven, right on about both Bear showing some useful things and taking some pretty dumb risks: the raft across and icy Andean lake; using a limestone cave to get through a rain forest; scaling almost every wall of rock or waterfall he sees; or deciding to descend inside a glacier. But he also provids some useful information.

Les, does some of the same things, like letting the sled dogs while crossing the Canadian north in winter, to really strand himself. He's got his own times when his info is not so good, like not knowing what to do for his foot rot in the episode when he runs back to the village because he thinks a jaguar is stalking him. He's got his own backup team too, although he seems to get less support than Bear.

There is some good info in both, but all of it should not simply be accepted as right.

And I'll admit both do a lot better than I would in most such situations.
