Bears are pretty cool. Have always been fascinated with them.I admit, grizzlies are a special breed. I flat out avoid them. There have been too many death by Grizzly in my neck of the woods but always by a threatened or compromized Grizzly. Thing is, you need a mighty big gun and you need to be very proficient with it,,,, plus fully composed to get the kill shot, you only get one shot before you are lunch.
The few horror stories of Grizzlys are terrifying, but few Grizzlies go down with one shot from the handgun of a panicked camper. Those horror stories often involve someone with a rifle after a few people are already dead.
ps... I love bears, I'd sooner carry a big knife and only use it if he was close enough.
Interesting that someone such as yourself, who knows how dangerous a threatened or compromised grizzly can be, would choose to protect themselves with a big knife. IMHO, if the grizz is close enough to use a knife, you are probably in more trouble than the knife can get you out of alive.
