Sean,
They both try to be monsters and succeed.
But to me, Oakland Hills tries to look too sophisticated, and suffers in that respect.
Oakmont just is. It is stark, and bleak, and unapologetic.
It doesn't need bunkers to have some sort of fussy shaping.
It doesn't need trees.
It doesn't need water hazards, or famous willow trees.
It doesn't ask to be understood, nor does it need to be. In fact, if you try to understand it, it will punch you in the face and knee you in the groin.
It's honest and it's out to get you, and your loved ones too.
