Pros:
Mix of open and wooded holes in an absolutely beautiful park! There are essentially no easy birdies here, unless you are playing some of the longer holes as par 4. To me, that is a pro.
Could be a con to others, though. If you like pitch-and-putt courses, this is not for you. Some of the long pins on longer holes warrant par 4, but some of the 4s out there should be 3s, IMO.
Cons:
Some might consider this course as "too open". I think the elevation changes and course features (island green on hole 4, et al.) trump that, though. The prairie can be a major pain when it's fully grown in the summer.
Other Thoughts:
This course is on its way to 4+ rating. Will be expanded to 27 holes in 2020. The beautiful, but problematic tees will be phased out in the near future, and replaced with a couple different styles. Once the slippery tees are replaced, and the next nine holes is in, this is easily a 4.
