Guys, there is a untold part of the story here. I live in Chattanooga, and several years ago I went camping with some friends of mine at Chilhowee. The place was trashed out from over-use by idiots, and ripe pickings for "trash" bears who became accustomed to a free meal. I had to emphasize to my friends (newbies to camping) that we were not doing any favors to the wildlife (or ourselves) by throwing food scraps out around our campsite.
I sopke with a Park Ranger the next morning after we camped, and he informed me that the forest service had been capturing and relocating other "trash" bears from the Great Smoky Mountains National Park to Chilhowee. The problem as he saw it, was "once a trash bear, always a trash bear". I thoroughly agreed.
I have been backpacking all over TN and GA, and have never had a problem with bears, wild pigs, or any other wildlife as long as I applied a little knowledge and common sense. But at Chilhowee, where car-camping is the norm, this was a disaster just waiting to happen. Bears are not cute cuddly pets, but ignorant campers don't know this and do stupid things that make the bears lose their instinctive fear of humans and come looking for an easy meal. The fact that campers are not allowed to carry weapons for self-defense only adds to the problem.
Don't get me wrong - I feel terrible for the family and their loss. But I am not surprised it happened; in fact I am surprised it hasn't happened sooner.
