To me the most remarkable thing about Grizzly Man is his girlfriend actually went after that bear with a frying pan during the attack. Because of a plane ticket dispute Treadwell goes back out into the heavily traversed "grizzly maze" late in the season after the salmon run when only the most desperately hungry bears were still there. He got that poor woman killed.
Speaking of which, the prospect of touring the remote West without SOME form of weapon at hand does make me uneasy. Humans have routinely gone armed in the woods since the beginning of time, seems unnatural to go without.
'Course at that point one has to balance probabilities with legal and moral liabilities. Anyhoo, bear spray is a given for me.
