TRURO, Mass. (AP) _ Vice President Al Gore's family vacation has forced the shutdown of an unsanctioned nude beach near the Cape Cod cottage where they are staying.

The Gores are at the summer home of New Republic publisher Martin Peretz. The home overlooks the Ballston Beach section of the Cape Cod National Seashore, normally the site of nude sunbathing and volleyball games.

A section of the beach has been closed while the Gores are in town. Park rangers and police have been enforcing the state and park bans on nude sunbathing.

Lee Baxandall, president of the Naturist Society and former Truro summer resident, used the publicity to plug for lifting the ban altogether.

``We urge Al to go down to the dune, strip off and enjoy the experience that ought to be available to all bathers,'' Baxandall told the Boston Herald. ``Bet that would loosen him up!''
