Pros:
A well maintained park. Quite a few signature holes, quite a few where the creek is a factor. My favorite is #15, which can be an easy hole. #15's tee shot is over the creek into a tree-lined fairway. The approach to #15 is usually easy but don't overshoot into the Big Creek. The finish is great, with a final cross-creek shot on #16, then #17 going under the bridge, and #18's basket tucked away in a hollow.
Cons:
Some older asphalt tees are in poor shape. However, most holes have newer concrete pads in more difficult positions. Hole#5 can get real muddy. There are numerous roads that are certainly OB during tournament play. A few holes get real close to picnic tables and popular non-golfing areas, be careful!!
Other Thoughts:
The course map on this website is the best available. Don't forget you have to cross the bridge after playing #6. The 7th tee is on the levee. The city of Hays has many hotels of all types/qualities. It is a perfect mid-point for long-trips through Kansas. It is amazing that in a vast sea of tree-less plains, this DGC works through a wonderful forest of tall/mature trees.
