I'm not really a good one to answer this but, several counties have hogs as well as several Wild Life Management Areas. There's not any hogs around where I live and hunt, or I would probably go crazy on'em. Try here:
www.state.tn.us/twra and you'll probably find something. Also Tn has changed hogs from a big game animal to a pest. It has got complicated to say the least. On private land, the land owner can shoot as many as he wants and he can have up to 10 hunters to help him out. Public land is different. You'll probably find something in the regs. There are several hunting preserves have hog hunting. You can pribably find some on the web. Good luck.
