Springfield, N.J., 1922
Having hosted both U.S. Opens and PGA Championships, this sturdy, leafy test is not for the faint of heart. Its 600-plus-yard par-5 17th was considered "untouchable" in two until the 1993 U.S. Open when John Daly blasted a 1-iron 303 yards to shatter that label. What the layout may lack in beauty it more than makes up for in toughness.

Rees Jones may have put the bite back in the Black, but Tillinghast gets credit for the bones of the layout, the only public course on the Tillie Top 10. The rolling terrain, brutally long par-4s, gigantic bunkers and speedy greens proved a worthy, if exhausting, test when Tiger Woods (shown here on the 15th hole) edged Phil Mickelson for the 2002 U.S. Open title.
