Isn't it against the law to carry in a National Park ?
Think I read that somewhere.
Since you're not allowed to bring guns into a national park, why not a chimpanzee? I mean, they're not only incredibly vicious animals when they're riled, but they're pretty damn strong as well. Several months ago some poor guy was attacked by chimps at an animal reserve and he had most of his fingers bitten off as well as an eye, his scalp, his face and a foot- they even mutilated his genitals (who knows what that was all about). Anyway, if you could convince a chimpanzee to go hiking with you, it would at least give you a fighting chance if a grizzly attacked. I'm not saying a chimp could beat a bear, but it would give you time to get the hell out of there. Admittedly, there may be some drawbacks (he might decide to go jump in a tree or something), but it's food for thought.
Hm, tough call. Judged by twelve, or eaten by bear...
