Same here in NC. We have a policeman at the admissions table asking everyone if they have a firearm. We actually have a law here where you can't carry concealed anyplace that charges admission, so even if the gunshow promoters didn't require it, state law does.
I'm not too concerned about it. It's easy enough to cut the zip tie with a pocket knife after I leave. The only problem is folks keep asking to buy my CCW.
Same here. I'm in NC and it is illegal to carry 1.)at a public gathering and 2.) any place that charges admission.
I usually bring a zippered gun rug with me and unload and zip up in the parking lot. Every dealer that is at least half awake wants to see what I got and wants to know how much I will take for it.
