Not trying to be "that guy", but the Handgunlaw.us link stated that Tennessee is NOT a must inform state...Tn has a .02 alcohol limit if you are a drinker. In other words, if you drink, don't be armed in public. Most bars kinda are gun free due to that law and rednecks of the past. lol Castle Doctrine also covers your car and motel rooms. I was living there when they passed the constitutional carry, What's different about it than here? oh and gun free signs are enforced. Also there is a duty to report. What they tell residents to do when pulled over to give your permit with your DL.
