The upscale community, on Long Island's North Shore and within the town of Oyster Bay, is a quiet village just 25 miles from Manhattan. Muttontown, like adjacent Brookville, was carved from large Gold Coast estates and is now home to affluent young families looking for good schools, tranquility, and privacy—not to mention great golf and tennis.
