Get out of the city and let the wind run through your hair for the day at the Knickerbocker Yacht Club in Port Washington, Long Island, as the guests of Christy and Bob Tanner.  Splash in the pool, bask in the sun, drink frozen daiquiris, and eat hamburgers from the snack bar that will take you back to either your misspent youthful summers --  or the last time you watched Caddyshack.
