The last time the U.S. Open was played at Merion, I was 8 years old. Therefore, I will exclude it through no fault of its own. I agree with the other four, and will substitute Pinehurst #2 instead. The 1999 U.S. Open at #2 is one of my all-time favorites. The contenders (Payne Stewart, Phil Mickelson, Tiger Woods, Vijay Singh, David Duval) were all outstanding, the play coming down the stretch superb, and the course was great. I wish they were all that exciting.
