I go in the back country alot in Wa state. I always carry a small arsnel with me to practice shooting. How ever is noted that meth heads and pot growers are in the fringe areas. The best way to protect your self from any proplems is to go in a group and bring a dog with you. A dog will always alert you to problems before you can. Bear spray is better defence than a handgun. We have black bears here and when they see you they run.
I had 3 kids that wanted my camp 2 years ago and were looking for trouble. I had my AR 15 next to me and they left.
We have to wait untill feb of next year to carry loaded firearm in national parks. (Obama signed the law a few weeks ago with the credit card law)
