PGA TOUR Pro Luke Donald waves a checkered flag as he ceremoniously sends off Cog Hill Golf & Country Club's 70-member grounds crew to ready the links for the 2009 BMW Championship in Lemont, IL on Tuesday, September 8, 2009. To prepare the course for Tiger Woods, defending champion Camilo Villegas and the world's top 70 players, the crew lays 1.8 million square feet of Kentucky blue grass and mows the entire course twice a day during the tournament, which takes place September 7-13.Photo taken by newscast for BMW.
