By rough count, 30,000 active beach driving permits have been issued to East Hampton Town residents. This is an astonishing number but more easily understood if you consider that old red-and-white stickers are valid until a truck is sold, same as with beach parking permits. In practice, nothing stops a resident from passing on a vehicle to someone from away, and because nonresident beach driving permits are priced at $275, some purchasers may just leave one on the bumper when a vehicle changes hands as a little deal-sweetener.
