Horrible! I have been to the Smokey’s many times. ALWAYS armed. Be it animal or human animal, there’s simply no one there to help you in many stretches of the woods. You are on your own...
I also have been to the Smokies many times. Hiked on the AT, Boulevard, and several other trails, sometimes alone, sometimes in a group. I was once pestered by a persistent bear, but have never sensed the least danger from any person. Freak assaults can happen anyplace. The Smokies are a very safe and friendly environment; frankly, I do not need the extra weight of a weapon.
