Nantucket Island Go native (for a day or two) From the April 22, 2002 Issue of New York Keep your oxford shirt on: Just because you're not invited to Lee Iacocca's house or Tommy Hilfiger's $4.6 million spread doesn't mean you can't wine and dine, bike and fish, or sail and swim on preppy Nantucket island. Your secret weapon is the Wauwinet, whose gray-shingled cottages feature wicker and antique furniture and whose nightly menu includes the island's trademark steamed littleneck clams and smoked Atlantic salmon with johnnycakes and caviar. For the nautically minded, there's whale-watching, deep-sea fishing, and sailing excursions; landlubbers can keep busy mountain biking, take a four-wheel-drive-jeep ride over 75 miles of trails, or don whites for tennis lessons with the inn's resident pro. To blend in better, shop for your Nantucket Reds (faded pink denim) at Murray's Toggery Shop, a local favorite. At night, crawl into bed under a handmade quilt to watch one of 500 movies, delivered to your door with a bucket of fresh popcorn. -- BETSY GOLDBERG Details The Wauwinet (summer rates from $400; 800-426-8718 or wauwinet.com); Murray's Toggery Shop (800-368-2134 or nantucketreds.com).
