I've been to this course before, at the 08 PGA Championship, albeit I wasn't really studying the course while I was there. While playing this course, I went straight to the holes that I remembered, the 5th, the 7th, 12th, and 18th. I also looked for some holes that I emulated, namely the 6th hole (Ross Society) and the 11th hole (Doak Valley). I wish I knew then what I knew now, because I appreciate this course so much more now. The 11th greensite alone, tucked in a saddle right below the 8th (I think?) green, is worth the price of admission.
Oakland Hills captures the feel of what we think of as parkland, country club, US Open-style golf, and this rendition captures the essence of the course and property in incredible fashion. The sheer amount of research, dedication, and hours that went into this course is what real course creation is all about. It's about living and breathing with the course for months at a time, until you understand all of the strategic elements, and exactly what the architect saw.
Due to the huge undulations in the greens here, it's probably not quite possible to match the exact real life conditions of the course. With that in mind, some elite players may be able to score well here in the right conditions. For the rest of us, pray for calm winds, and make sure you find the fairway (no light rough) and the right quadrant of the green.
