However, any person eligible to legally possess firearms may openly carry unloaded firearms that are not cased specifically "When going to or from the person's private residence or vehicle or a vehicle in which the person is riding as a passenger to a place designated or authorized for firearms repairs or reconditioning, or for firearms trade, sale, or barter, or gunsmith, or hunting animals or fowl, or hunter safety course, or target shooting, or skeet or trap shooting or any recognized firearms activity or event and while in such places". Only under these circumstances may individuals carry unloaded firearms publicly that are not cased.
