I’m not trying to rain on your opening round or poop on your teebox, but par today at Oakmont is 71 for members and was 72 for the US Open when Ben Hogan won in 1953. So a large part of the USGA’s defenses for the course are accounting irregularites.
Minus 12 (or -13 w/o penalty) for DJ shows those defenses have been badly degraded when compared on an apples to apples basis to earlier US Opens played at Oakmont.
A great course? Yes, but really not all that exceptional.
Well then. I am truly curious as to what course you do believe is “exceptional”?
