Sean--
Hawk's Ridge is a teriffic Bob Cupp design, the best work I've seen from him. He had a great site to work with, nice and rolling with a couple of creeks and a large lake dug by the Army Corp of Engineers to work with.
The one thing that stuck out in my mind were the greens. Cupp did a great job contouring to greens to create some interesting putts if you are on the wrong section of the green, particularly given that they will be on the quick side. There are quite a few little subtle breaks throughout too. It took me a couple of looks and some caddie assistance to totally figure them out. Standout greens: 8, 9, 11, 15, and 16.
There are some notable holes, particularly the stretch from 2-6 where there is some real excitement with chances to make birdies and major mistakes. The drivable par four sixth has drawn mixed reviews from people I've talked to, but I really liked it, any score is possible there. The 14th hole is excellent with a couple of bunkers fronting the green that look like they are next to the green from the fairway, but are really 20 yards short. The par five finishing hole is cool too, with a pretty tight landing area for the bombers that want to reach the green.
I would describe Hawk's Ridge as an exciting course that will definitely get your blood moving. Would strongly advise against playing the tips, they are really long, particularly given the wet summer and from what I've been told, none of the members go back there. The atmosphere is great too, very laid back and comfortable.
