In wonderful Ohio, they sell you steel plates (made by convicts) and then sell stickers for about the same price every year. When your steel succumbs to rust/discoloration, you can then get a ticket for that and then get to buy new steel plates to start the process over. Many local municipalities use the front plate as reason for a traffic stop and then go fishing. So....if you are the least bit illegal, conform and use plate IMO. I've relocated on cars that I didn't like factory location with some aluminum stock fastened to factory fasteners and pop rivets to plate. FOP stickers help?
