I have a niece who works for the U.S. Forest Service in Alaska, and when she is on the job and out in the woods, she always packs at least a .44 magnum revolver. There be grizzlies and other critters that have big teeth in them there woods, you see.
I agree with that. I spend lots of time out in isolated areas, and have learned that it is better to be safe than sorry.
I am not in mountain lion country, and wouldn't care being in that setting. But, I'd be sure to have the means necessary to protect myself.
