Absolutely. The Smoky Mountains used to be full of them. Some folks imported some Russians a good while back to stock their hunting preserve up on one of the balds that is now inside the park. They escaped and became very common in the area. The park folks eventually went on a rampage against them trapping and shooting them. To get back to the original topic, a class mate of mine in a Botany class at UTK was studying how to eradicate them and was hired by the park service so that he could legally hike through the woods and shoot them. They even gave him a uniform that they warned him never to wear in the woods. He was hiking along the AT one day with his Ruger 44 Carbine sticking out of his pack and stopped by a spring to fill his canteen and to take a breather. It was not long before this scruffy looking fellow appeared out of the woods and came over to talk with him. The man had no gear at all with him and was very curious about how the hunting was. My class mate gave a brief hunting report without disclosing that he worked for the park service. After a while, several other men appeared out of the woods with their gear and firearms to join in the conversation. They all chatted a while before going their separate ways. The men had remained hidden in the woods to check out my class mate to make sure he was a fellow poacher. It scared the willies out of my class mate because he was convinced that his life would have ended right there if they found out he was working for the park service. The woods are full of meth labs (there was one on Oak Island several years ago near the Food Lion), moonshine stills, pot fields, ginseng hunters, poachers, and several other groups of people who would as soon shoot you as look at you.
