I would certainly remove Prairie Club Dunes and replace with Dismal River Red. Dismal Red is vastly underrated and I'm not sure why.
Is it?
I like Dismal Red. I especially love the intimacy of the routing in such a vast environment, and that it has such a completely different feel from the White course. But I'd split 10 plays 9-1 with the Dunes at Prairie Club, which I continue to rate as one of the most varied, elastic, and compelling courses I've ever played. Between the two courses, I think Prairie Club has:
* The four best par 3s. I'm still waiting for one person to make a coherent argument for why the Dunes course, as a set, should not be considered to have one of the best sets of par 3s in the US. They move in different (wind) directions, play to a variety of lengths, and they're all holes where consideration of ground contours can lead to aiming well away from the flag to get close to any given pin, whether off the tee or when attempting a recovery. When I think "best fourth hole I've played," PC(D)'s 4th always comes to mind right away.
* The 3 best par 4s. Dismal Red is full of very good two shotters, but I don't quite like any of them as much as 2, 8, or 13 at PC(D).
* A superior set of par 5s - 10 and 12 in particular at PC(D) are excellent holes. The par 5s at Dismal Red are fun, but not the stars of the show in my mind.
I love Dismal Red too. It's an outstanding routing and a delightfully sporty course. I do have it above quite a few courses on this list, in a comparable tier to Mammoth Dunes, Whistling Straits, Moraine, Kingsley, and Cherry Hills. I'd actually probably rate it above all of those courses, personally, but I can't be too frustrated about it not being included because ultimately I think those courses are all pretty comparable in quality, none of them are no-brainer top 100 courses in my mind, and some of them will inevitably get squeezed out of a list like this.
I was recalling the days back before Ran and Tom Doak had played Harvester Club with a friend over the weekend, remembering that when it was announced that Harvester would be closing as a public course, the immediate GCA reaction was that it was just another average CCFAD that didn't make it. I was astonished at the time as a guy who had always loved the course. It's inconceivable to think about guys around here calling it "average" now that Doak has called it the best course in Iowa, and Ran has written a glowing review of it under Courses By Country. But before the tastemakers played it, nobody had a "correct" opinion to parrot.
Well, Tom Doak still hasn't been to Prairie Club and Ran hasn't profiled it. In the absence of visits from them, I've been waiting 10 years for someone to give me a coherent explanation of WHY it doesn't belong on any given top 100 list, or WHY it's better or worse than anything else in the Sandhills region. And still, the best I get is "Dismal Red is underrated" or "LOL." In fairness, the turf conditions at Prairie Club could be firmer and faster, more regularly. Then again, so could the turf conditions at Dismal in my experience.
