TN recognizes all other HCPs/CCWs so open carry, conceal, part conceal... whatever you want. In TN, you are required to present your HCP upon request of an LEO. Vehicle carry laws were recently modified to no permit required but that's a non issue for you. Enjoy!
Last time i was stopped by an LEO and started to tell him, he cut me off mid sentence and said "you arent required to inform in TN and if you arent carrying in memphis, you're a dumbass and deserve to get shot!" haha.
