Well Ben, you can now add me to the list of folks that have played Diamond Springs.
I agree with most of what has been said. It is an incredibly fun course. The decisions on mowing (basically one cut everywhere by the green and the junk) give it a unique look and must cut down on maintenance expense. The greens had all sorts of wonderful quirk, with some real challenges (#2 was almost like Crystal Downs #7 rotated 90 degrees; the first par three had three distinct tiers, each presenting their own challenges). The course was wide, but put a premium on angles and approaches (especially on a few of those greens). The use of the ravines on a number of holes was a blast and it even gave me a chance to try to drive the green on a short par 4 that was a hero/zero type shot. The pro was very welcoming and the course was wide open. On top of all that, the price was right ($37, which came with a cart)!
There were a few negatives (which may be due in part to location and in part the low greens fees). First, the course was playing very soft and wet. It seems like it calls for an F&F set up and I was disappointed and how soft it played. I was under the impression that the ravines and dunes were all sand based, so I would have thought the course drained well. Second, the greens were quite slow. Given some of the slope on a few of the greens, I wasn't looking for Oakmont, but you really had to crush the ball to get it to the hole. Finally, my twosome was the only group out there walking the course! When we asked about walking in the pro shop, we got a quizzical look and two quick questions "1. you do realize that your greens fee comes with a cart, right? 2. Do you normally walk 18 holes?"
In any event, I highly recommend Diamond Spring when in the greater Saugatuck area. Well worth driving directly past the Ravines to get to DS.
