Well Michael you beat me to it.
I also played in the Wiliams and have to agree with everything you mentioned. The last day was pouring rain much of the day and the 13th green started to puddle and out came 10 workers with squeegees to make sure we could get the round in. We played fairly well and finished 4th in the event and too have no idea how you shoot 63 with that course set up. We got to play the exact pins as the PGA Championship from the Wil-am on Wed to the final round on Saturday.
I am glad to hear that they already have plans to soften the back of 15 because it really is unfair to have the left side of the green fall off of the green, especially when you have hit a solid and safe shot to that treacherous back pin location.
FWIW, I also drove down to Philly and played Merion on Sunday morning. They have also left the US Open fairways in tact. The back tee on #3 is a bit much, the one on #5 is terrific. Moving the fairway towards the creek on #11 didn't seem to enhance the hole, and in my opinion actually made the hole worse, no advantage was gained by challenging the hazard on the left because there is a tree that blocks out most of the green from what is now the left edge of the fairway. I also didn't like the change on 15, moving the bunkers in towards the road, and they are planning to move at least one of them back to the right.
All in all, a great trip, seeing both courses in their major set up was interesting to say the least.
Condition-wise, Merion's bent grass greens were superior to Oak Hill's poa/bent combo but Oak Hill's bent grass fairways were better than Merions. Don't get me wrong, both courses were in terrific shape.
On a side note, I got lost wandering around the clubhouse at Oak Hill only to find 8 lanes of bowling alley on the bottom floor, pretty cool. I was also fortunate enough to get to see the archive room at Merion, which was really interesting as well.
Michael, I will look for you next year.
