Let me first welcome you to OCDO and then recommend that you read the
Forum Rules.
I particularly point out rule #14:
(14) LONG GUN CARRY IS OFF-TOPIC: This web site is focused on the right to openly carry properly holstered handguns in daily American life. We do NOT promote the carry of long guns. Long guns are great! OCDO co-founders John & Mike and most of the members of this forum own at least one long gun - but due to urban area issues of muzzle control, lack of trigger guard coverage, and the fact that the long gun carry issue distracts from
our main mission to promote the open carry of handguns in daily life, we will leave long gun carry activism in the capable hands of the future founders of web sites about long gun carry.
I moved this thread to the Tennessee sub-forum so that you may get a state specific answer. I think that Tennessee prohibits the open carrying of loaded long guns, but not unloaded ones, but confirmation evades me. I will leave this thread open for someone to provide the answer with a cite. I assure you if this thread goes beyond those limitations it will be closed.
Now how about OCing a handgun and meet up with like minded people at some of the local events?
