I didn't see that Peter had anything against guns per se. Actually, he said he liked guns and spoke fondly of a certain .338.

I had caribou stew tonight. From Adak in the Aleutians which I schlepped out from the hunt last Fall.
One can appreciate guns as tools for certain tasks, look at the evidence of scores of bear encounters and conclude that I, personally, am going to carry spray (if anything) and make a lot of noise (always).
No one is telling you not to carry a gun. I'm always telling people to do whatever approach they want. HYOH. I'm not going to stop someone from bringing their grandfather's canvas umbrella tent. It's how I started camping. But I'll point out that a nylon dome tent, sil-nylon tarp, etc, is lighter and more effective. Cause it's a forum for discussion of various issues.
I've looked at published research, talked to lots of people (except for that patient of my wife's who squeezed off a rifle round, clipped some brown bear hairs and drew some blood because he was, well, dead from a chomped skull), and pondered all the grizzly experiences we've had and the ones we've avoided having.
For myself: Always noise. And being alert to my surroundings. Spray in a higher-threat time and place. Guns, for me, only if I'm going for some bear sausage, roast, etc. Like 6 weeks ago.
But to each their own.
