From the Frequently Asked Questions page of the Crossroads of the West Gun Shows:
Q: Can I bring a gun to the show to sell or trade? A: Yes, and many folks do. Please be sure the gun is unloaded before you enter the building, and take it to our gun check table at the show entry for verification. They will clear it and secure it with a nylon tie to disable the action. No loaded firearms and no loaded magazines are permitted in any Crossroads gun show. Your personal safety is our number one priority while you are at the show.
Q: Can I carry a loaded gun in the gun show? I have a Concealed Carry Permit. A: We respectfully request that you do not bring any loaded firearm into the gun show. Safety is our Number One Priority, and a safe environment in the show can only be maintained if there are no loaded guns in the show.
