I do love these bear threads!
First about statistics in general: I don't trust them, it seems that anymore people are so polarized and fervent in their opinions that fudging on data presentation is more a matter of ultimately bringing the truth to the unwashed than reprehensible lying. And then, even if the statistic was the very best that somebody could do, honestly presented, you're still dealing with a bunch of people's experience. Having watched humanity most of my life, they really are a sloppy half-arsed crew. Within the limited range of things that I do, I'm a bunch better than that.
If I were to look to any group to act as a object lesson, I'd want to know what Alaskan guides carry to protect themselves and their clients.
Looking back at the start of this thread, Mihun posed several scenarios, in them the person was pretty well screwed from the start. The bear spray guy was suggesting that the bear was a freight train. Now, all this might be fun and dramatic but I'd suggest that none of these situations would have started from a full on attack at the beginning. Oh...to be fair, if you stepped between an unsuspecting momma bear and her cub in the middle of a berry patch you'd probably be killed and find yourself ragged arsed and chewed up, talking to St. Peter before you knew you were in trouble. But most times in situations between humans and bears it doesn't play out like that.
Actually, thinking about it while I'm typing here, pretty much always there's some time otherwise all this talk about "what to do about bears" wouldn't ever happen. You'd worry about bear attacks just about like lightening from a clear sky.
I'm not trying to convert anybody to shotguns and if it ever comes down to it I hope that whatever someone selects works for them. For me, my shotgun is the most lethal thing I can carry and presented with a situation where my future is in doubt, it's the thing I want in my hands. Then watching the bear over the barrel, if I have time I'll load a rubber slug shell, and offer him a reason why it's a bad idea to continue.
Best Wishes, Rob
