Merion Golf Club, Ardmore, PA

The Merion Golf Club, near Haverford and Bryn Mawr Colleges, in the northwestern suburbs of Philadelphia, has two courses, though only the east one, Merion East, is considered a classic, and has hosted five U.S. Open tournaments. It is dog-legged in the middle, and split by Ardmore Avenue, which has to be crossed to play through.
