Nantucket Beach Permits are a sticker you buy ($100 per year) to put on your vehicle so you can drive (4X4 ONLY) on the Nantucket sand right onto the beach. In certain areas of the beach. I am obsessed with taking pictures of these stickers piled up on the car(s) as this one has in the picture. And I mean these cars are from all over the country. For those of you that are not in Nantucket.....You may see someone with it on there car one time .. somewhere.. in the USA! Now you know why I am gonna post them when I see them :) Love it!
