IT'S a barefoot society, car-free and carefree, but as long as anyone can remember, Fire Island, the skinny sandspit stretched along the underside of Long Island, has had its distinctive hierarchy. At the top are the natives, flinty souls who live year round on the 32-mile-long barrier island between the end of Robert Moses State Park and Moriches Inlet, where the Hamptons begin. The natives, it is said, look down on the homeowners and other summer folk who seasonally throng the roughly two dozen communities. The homeowners turn up their noses at the renters. The renters disdain the groupers who chip in for housing shares. And all feel superior to the day-trippers who sail in on the morning ferries and sail out again in the evening.
Which left us somewhere near the bottom -- hotel guests on Fire Island. Yes, there are hotels on Fire Island. No, you wouldn't generally pick them over a house. But between a hotel and nothing, the choice was clear. For five days, my wife and I and our two girls sampled the many delights of New York's quasi Key West with its own rich social and cultural history. We breathed the same fresh salt air and patronized the same restaurants and shops as any third-generation islander. We splashed in the same roiling surf, hunted for the same horseshoe crabs and shells on long stretches of deserted beach, strolled and bicycled the same few blocks between the bay and beach and took the same water taxis to the same outlying communities. And we felt entirely welcome. Indeed, there is probably only one restrictive community, Point O'Woods, where outsiders, whether natives or off-islanders, may get the cold shoulder; but even here we carried out a beach-based incursion without incident.
Yet a word of caution. To book a hotel on Fire Island on a summer weekend is to cast one's fate not to the winds but the singles. A commune of wildly celebrating youth in a Fire Island group house can be noisy, but when the party is compressed into a thin-walled hotel room, the disruption can be truly hellish, as we found out on our last night in Ocean Bay Park. Still, some hotel managements are laxer than others. And Friday and Saturday nights are definitely wilder; weekdays can be positively idyllic.
The first thing many new visitors want to know is where the name Fire Island comes from. The truth is, nobody knows. Some have linked it to the signal fires of whalers or wreckers who tried to lure ships ashore for plunder, or to the onetime fiery stands of poison ivy. Others say it grew out of a misreading on early Dutch maps of vier, or four, islands. Either way, the name, accurately enough, evokes blissful summer vistas of burning sands and blazing sun as well as the constant peril of fire.
Resort development began in the 1890's with the establishment of a Chautauqua Assembly, a movement for Christian betterment through learning and the arts, in what became Point O'Woods. In the early 1900's, just to the west, developers bought up tracts and began selling vacation lots to Brooklynites and other confined city folk for what became the village of Ocean Beach, Fire Island's de facto capital. Served by growing ferry links across Great South Bay, birds of a feather flocked to like-minded communities: boat owners to Saltaire, fishery workers to Seaview, casino-lovers to Ocean Bay Park, families to Kismet. Homosexuals driven from other communities found a welcome in Cherry Grove, creating one of the earliest centers of gay life in the nation.

Stars and Salons
Stars of the Broadway stage, stalwarts of the Algonquin Round Table, artists, bohemians and assorted hangers-on soon found their way to the quirky seasonal salons of Fire Island, where the politics were often decidedly leftist, and a Marxist group house might well blackball an applicant rumored to be a Trotskyite. Irving Berlin, Fanny Brice, Clifford Odets, Truman Capote, Tennessee Williams, Jimmy Durante, Woody Allen, Lee Strasberg and Marilyn Monroe all made their way there, as did Mel Brooks and Carl Reiner, who honed their ''2,000-Year-Old Man'' routine on dinner audiences. And everyone mobilized in the early 1960's to thwart Robert Moses's plan to build an access road through Fire Island.
