Well, considering I started this thread critisizing spray, should share my thoughts.
We are, as a lot, overly trigger happy much to the detriment of bears- especially Grizzlies. I've been bluff charged, and it was my fault, I got in the bubble and knew the bear was there. The bear's fine, my shorts didn't fare as well. Unfortunately, bluff charges are one of a disgruntled bear's communication methods, and it often leads to the bear's death when it wasn't necessary. Everybody wants a charge story, which also doesn't help the bears survive. I see the guy who holds his ground on a bluff charge and doesn't pull the trigger in a better light than the fellow who shoots first, asks questions later. I've been spending time in southern BC lately and it is so sad compared to up here, there's almost nothing left. A few straggling bears, but not the hordes you see populating every open area up north in spring. I'd like to hope the southern mentality of years gone by, that being a complete lack of understanding of bears and their behavior with tragic consequences, doesn't invade the north and cause the same thing up here by the time my sons have kids. It could happen, places aren't wild without their big predators, it's what I always look for anywhere in the world to get a feel for how wild a land is.
This said, I don't like spray from what I've seen, and if the situation is proper dire, gun is my preference. I just won't rush to shoot and hope others think the same way.
