New to the world of guns, I live in Texas and bought a handgun. I have family in Tennessee and may fly out to visit in the upcoming months. Only interested in target shooting and maybe plinking in their backyard (they live in the middle of nowhere) Questions 1)Does TN have the same gun laws as TX where you don't need a permit to carry a gun in the car as long as it is not accessible? 2)To fly with the gun, seems like I need a hard case that is lockable. Do I need to declare the gun when I buy the ticket or can I just show up the day of the flight with it locked up? 3)Anything else obvious I'm missing.
