I go to the Bill Goodman Gun Show in Nashville, TN and they check all firearms and magazines at the door, also if you bring in ammo to trade, it must be in a container. It doesn't bother me any because there are lots of people that just pick up any gun that they like and start pulling the trigger
. With "responsibility" like that, I have no problems with the officials checking everyone on their way in, each time. Great gun show though.
