We went to the gun show. Everyone who has been top gun show knows that they don't allow loaded guns or loaded magazines. So this guy comes in and questions the guy at the front desk, who was also a cop, saying he had a HCP. The cop said that his HCP was invalid in POSTED areas, which is true. The problem is that the gun show was not posted properly and thus not a valid GFZ. They can ask you to leave, but carrying a loaded gun inside is not breaking the law as the cop suggested.
