Play Golf America program. The Professional Golf Association (PGA) and Golf Digest have developed the Play Golf America program, in which teaching professionals at participating golf clubs provide a free 10-minute lesson to new cus- tomers. According to Golf Digest (July 2008), golf facilities that participate in the program gain, on average, $2,400 in green fees, lessons, or equip- ment expenditures. A teaching professional at a golf club believes that the average gain in green fees, lessons, or equipment expenditures for par- ticipating golf facilities exceeds $2,400.
