I was at the Harvest Festival in New Roads this weekend and saw signs that said "absolutely no weapons.. You will be searched". They had "checkpoints" if you want to call them that.. wanding people for weapons on the Main Street which if I'm not mistaken is a state hwy. Can the city of New Roads arbitrarily create a firearms free zone on a state or city road? I'm just wondering how that type of thing works. What are the laws regarding any type of carrying on a public/state road during a festival?
