Some states have banned using that plastic strip since it is not premanently afixed to the dingy AND that it may be easily stolen and put on a "hot" dingy. I tried the strips, but one of them broke easily in handling the dingy launch. I got a nice number set from Accent Graphic in Annapolis. The make a nice dingy set that includes squares to put your state sticker on. Made of something like rip-stop fabric with an adhesive, they are flexible and have stuck well for the three years I've had mine. A.G.: 410-268-6411. Maybe other graphics shops can make them, but try the BoatUS/graphics site also.
