Host to several prestigious U.S. Opens, its famous seventh hole is considered by experts to be one of the most challenging and beautiful par 3's in existence. It plays downhill to a green squeezed onto a tiny spit of land, a green on which waves crash, a green which at its narrowest point is only 8 steps wide. It's the shortest hole in major championship golf, but yard for yard, it is the hardest hole in the world.
