Thank you, Medicine Woman. I like the guy wire idea!
Actually, for whatever reason, I simply decided I wasn't going to be afraid of bears. The moment came when -- of all things -- I was driving back from the grocery store and contemplating the deliciousness of the smoke pouring from Little Richard's Barbecue (perhaps it's a top-of-the-food-chain thing) and a little switch in my head flipped. All of a sudden and from out of nowhere the ongoing bear monolog popped to the front of my mind but this time it was, "Screw it. I'm just not going to be afraid."
There wasn't any rationalizations (actual bear attacks are few and far between, for instance) or acquiescence ("Well, as long as I hang my food correctly and don't slather myself in beef gravy or brush my teeth with beef jerky, then I've done all I can do") -- the whole bear fear thing was simply done and I don't know why.
Sometimes there's no figuring the human brain.
