Not in Maine, but this gun show business is getting tiresome. I thoroughly dislike having to unholster, unload, and let some moron zip tie my weapon. I call them "moron" because the last couple of guys had no earthly idea what they were doing and I had to zip tie the weapon myself.
I don't think I'll be going to any gun shows in the foreseeable future because of this. About the only thing that is cheaper at the gun shows around here is some of the ammunition.
