That's the type of bear I worry/caution others about.
Imagine what would of happened if the guy hadn't had the Bear Spray and kept his cool. :'(

Unless your prepared to go hand to hand with a bear like this, at the minimum you need some bear spray, preferably the biggest size they make.

In the BWCA I'd pack a magnum handgun as well, especially if traveling solo.

What this tells me too is how smart they are.
After a couple of attempts it learned to fear the spray and backed off when threatened with it.

I'm sure that given enough time and distance it would of figured out that the rapidly depleting bear spray was no longer a threat and went in for the kill.

Big bear against Leatherman, I wouldn't want those odds. :P
