So, what gives with the "do your potty business well away from camp?" I've never heard of that before.

I've heard of the "triangle" method where you camp in one place, store your food in another, and cook in a third spot, all about 100 yards apart, but I've never heard that bears are attracted to human waste.

And what about pepper spray for black bears. If one did catch a bear going after one's food, would pepper spray be a good idea or are you "asking for it" (risking that the bear would turn on you)?
