Pros:
Great course, every hole is unique. Good balance of open and wooded holes, fun to walk and challenging to conquer. Almost no hole is straightforward; interesting tree placement and water hazards force you to think about every tee off. I've never seen a basket hanging from a tree, or a basket 12 feet high out of a stump, but you'll find them here!
Other Thoughts:
All 18 holes have concrete pads and signage. I've played many courses in the KC area (Rosedale Down Under, Swope Park, Heritage, etc). Garnett is my favorite. It is challenging, varied, and simply unique.
