Dude was supposedly an anti bear hunt activist.

I know this was a situation of being too close to a cache, and not just happening onto it but some of the comments here are willfully ignorant. I have been humbled a few times as to how close a grizzly can get before you know he's there. Getting a couple shots off beforehand, even if your rifle is on your body isn't always feasible, if you're ready for it or not.
