Ok they are playing the we have an explosives permit and because of that you can not have a gun on the property. Well, wouldn't that include visitors? I know of a few accounts were people were made and asked to either lock it in there car or leave it locked in the security office until they left. If their permits for the fireworks really excluded guns on the property wouldn't they have to ask those people to remove the gun from the property??
