I was wondering when he'd do the "hey bear" thing. That's what I was taught to do if I saw a grizzly. You back up and go "hey bear hey" in a really low voice... It's kind of funny to actually see someone do it.
I've never been this close, but I've been close. Looks like he's up by Denali, in which case not having a gun and a noise maker was a pretty stupid decision on his part. Best thing to have with you is a cowbell - scares the shit out of them.
It seems somehow unfair to censor the swearing. If there's one time in your life you should get to swear and have people let it go, it's when you're damn close to a bear.
