I am in love!
Just played The Quarry this past week and wow, that is impressive. As others have said, the conditioning is about as good as possible. You can't even find a divot anywhere as they pick up all divots after each shot and put it into a divot bag (a first for me). The routing is predicated on uphill/downhill with 10 being a favorite of mine for sure and a rare beautiful uphill hole. It was just a couple days off overseed and cartpaths only, the GM was apologetic as he said this is about the worst I could see the course. Greens were not fast (probably 9-10 at most) with the greens having mild slope to them, but very fair. I don't recall an unfair pin placement although there weren't many flat putting areas, with some tilt to the greens. You have to know the Palm Springs valley where everything breaks to Indio and the mountain.
The fairways were very generous considering it is a desert course, although not a true desert course for they have rough and even that is like the 1st cut at Augusta National.
The Short Course is really unlike anything I have seen. They have a 10 hole TF short course which are all par 3's, although three of the holes can be turned into par 4's from different tees. It is not widely photographed or publicized and the GM says they don't allow it, it is strictly for the members enjoyment. I can see why as it is visually almost overwhelming with the scenery of palm trees/ flowers/ mountains, streams, etc. Gorgeous course. I played Hamilton Farm this summer which had the only 18 hole par 3 course rated by the USGA apparently. The Short Course exceeded that on visual eye candy alone. Many members go and walk the short course with their dogs or just for exercise and dont' play it as much. Almost like a nature walk and what a walk it is.
This is definitely being considered as a daily course for me to retire to in 4-5 years. The staff was welcoming as you would expect but very talkative and genuinely nice people. The 10 or so members I met, besides being retired from their extremely successful careers, loved talking NFL football, sports, and ribbing each other. Pretty unpretentious group, which isn't what you would think at a high end club in Palm Springs.
Also a side note is that yes they have homes on the course, but only 47 are built out of a possible 105 I believe. more than half are on the Short Course and those on the main course are set back quite a bit, very tranquil not seeing homes.
So I admit I was very impressed and can see why the raters love it for conditioning, although it is not a difficult course by any means with a pedestrian 128 slope from the blue tees. If I was a mid to low single digit handicap it wouldn't be as challenging certainly. I don't have that problem and doubt I will when I retire.
Two thumbs up for The Quarry as for the site it was built on TF did one of his best work IMO. This probably passes Galloway National for TF's I have played.
