Golf course

A golf course consists of a series of holes, each with a teeing ground that is set off by two markers showing
the bounds of the legal tee area, fairway, rough and other hazards, and the putting green surrounded by the
fringe with the pin (normally a flagstick) and cup.The levels of grass are varied to increase difficulty, or to
allow for putting in the case of the green. While many holes are designed with a direct line-of-sight from the
teeing area to the green, some holes may bend either to the left or to the right. This is commonly called
a "dogleg", in reference to a dog's knee. The hole is called a "dogleg left" if the hole
angles leftwards and "dogleg right" if it bends right. Sometimes, a hole's direction may
bend twice; this is called a "double dogleg".A typical golf course consists of eighteen holes but nine-hole
courses are common and can be played twice through for a full round of eighteen holes.Early Scottish golf courses
were primarily laid out on links land, soil covered sand dunes directly inland from beaches.
This gave rise to the term golf links, particularly applied to seaside courses and those built on naturally
sandy soil inland.
