Bob,
There are wild hogs in Tennesee in the Smokies. I have not hunted these but from what I have read and heard the population is not such that you will find them in any great quantity. Best methoed there seems to be using dogs. High density hog hunting is further south Georgia, Carolinas,Florida, parts of Arkansa and Oklahoma and of course Texas. If it is just a preserve hog hunt your looking for there are lots of places closer to you. There is a big preserve in northern Michigan - Cheyboygan perhaps some of the michigan guys could give you contact info. Nugent used to own place but not sure any more on that. It's still open as I seen the sign last month driving through area. These preserves are best termed as a fun BBQ harvest at best. Wild hog hunt they are not. I would highly recommend you head further south for real hog action.
