I've seen some pretty good footage of a bears, and not just from this guy, of course after more than ten years you are going to compile some good shots.
Their getting munched had nothing to do with a teenage punk bear. This bear came down for food, was late in the year, and not having much left, ate both of them. He didn't just go to mess with them, the bear actually ate many of their body parts.
I forgot his name, but there was once a real Grizzley man, who wasn't crazy, and did real research... I wish I could remember his name. There is footage of him, his camp surrounded by I think four juvenile grizzlys, which he bluff charges a few times to get rid of them. Crazy people are crazy, doing something to stay alive with bears that arent used to you being around, that is a whole different story.
