Did anyone else read the reason they kept moving? They were afraid of the wolves tracking them? Wolves are notorious for following a human's trail simply because it is easier for them to walk through the snow. I know there have been a few wolf attacks in history, but AFAIK they are quite rare. Had the couple stayed put, they would have retained much more energy and they could have made more elaborate signaling, etc.

Heck, even if the wolves were surrounding them, it would be easier to spot from the air.

Any wolf experts on the board who'd like to educate me on the "dangers" of wolves? I've had a wolf at 10 paces, and I've got the video to prove it. Not scary at all. 'Course, I'm usually pretty well armed.
