"That's interesting. I've never seen a bear chew through any limb bigger than 3 inches."
Me neither, but this guy was a carpenter and I wasn't about to dispute his estimate of thickness. Matter of fact, I haven't seen a bear chew through a branch, period. It's a minor point of pride with me that I haven't had a run in with bears since two closely spaced incidents during my first two years of backpacking. The whole point, as far as I'm concerned, is to be where they're not. Generally, that means high and remote or, in the Cascades, remote. Those are the places I love anyway, so it's no sacrifice as far as I'm concerned.
