New York is a sports lover's town. A rousing evening with the Yankees or Mets is a night to remember-especially when guests are ensconced in a private skybox complete with an elegant buffet. (Prime stadium seating with your very own vendor passing out hot dogs, ice cream and frosty beer might be slightly less lofty, but it's just as memorable.) Thoroughbred excitement is always in the air at our Day at the Races. The U.S. Open is surely the winning ticket for every tennis buff.
