Urban wisdom, only partly true, namely when it's a surprise encounter. If it's been following and watching you, though, it sees you as prey, and you're in trouble, so you go on the offensive. Charge, throw rocks, make noise, spread your jacket - or if you're smart, you brought pepper spray or your 9 mil. They've pulled plenty of chunks of people out of bears' stomachs. And burying is what they do to a carcase to keep it from other animals. I may be vegan, but I'm smart enough to carry my UDAP and pistol in the back country.
