[PAR] [TLE] 2009 U.S. Open (golf) [SEP] The 2009 United States Open Championship was the 109th U.S. Open, held June 18–22 on the Black Course of Bethpage State Park on Long Island, in Farmingdale, New York.  Lucas Glover won his only major title, two strokes ahead of runners-up Ricky Barnes, David Duval, and Phil Mickelson. [PAR] [TLE] Long Island [SEP] The Long Island is a large, densely-populated island off the East Coast of the United States, beginning at New York Harbor just 0.35 miles (0.56 km) from Manhattan Island and extending eastward into the Atlantic Ocean.  The island comprises four counties in the U.S. state of New York: Kings and Queens (which comprise the New York City boroughs of Brooklyn and Queens, respectively) to the west; and Nassau and Suffolk to the east.  However, many people in the New York metropolitan area (even those living in Brooklyn and Queens) colloquially use the term "Long Island" (or "The Island") exclusively to refer to the Nassau–Suffolk county area collectively, which is mainly suburban in character.  The majority of New York City residents now live on Long Island.
