Golf is a sport in which an individual attempts to hit balls in a number of holes, using clubs, on a golf course. The idea is to use the fewest number of strokes to reach the target. It is a very popular sport all over the world. However, playing at privately owned greens can be quite an expensive affair, or even impossible without membership in exclusive clubs. A public golf course, such as the one in Rocky Face, is maintained by the local corporation or governing body. It can be used freely by enthusiasts of the game, perhaps for a small fee. The green can be constructed and laid out in different ways. The number of holes may also differ.
