Merion Golf Club, host of the 2013 US Open, is located in Haverford Township, PA and is a private golf club.
Becoming a member of Merion Golf Club is rather difficult. Potential members are required to play a round of golf so that a small committee of members can evaluate talent level (or handicap), as well as etiquette to ensure that golfer will act respectively around other members. Initiations fees are also quite steep, although it is uncertain as to how much those dues cost. Ultimately, Merion is quite exclusive and difficult to join as a new member.
