Disc golf, also known as Frolf, Folf, Frisbee disc or frisbee golf, is a flying disc game, as well as a precision and accuracy sport, in which individual players throw a flying disc at a target. According to Paul Ince of the Professional Disc Golf Association, "the object of the game is to traverse a course from beginning to end in the fewest number of throws of the disc." In just 8 years (2000–08), the number of disc golf courses doubled.
