Tennessee doesn't seem so bad. They have full reciprocity for CCW. 'No Guns' signs do have the force of law, which kind of sucks. Also, when I worked in Murfreesboro, they have a local ordinance that forbids firing center-fire rifles on Sundays. The local ranges all have big signs with copies of the law, and patrol the lanes pretty diligently to make sure nobody shoots a center-fire rifle, as the range apparently gets fined if someone rats them out.

Illinois pretty much universally sucks for guns.
