-Proof that a course doesn't have to have massive elevation changes to be challenging. There are some great holes here, even in pancake-like Kansas
-Nice use of natural obstacles - the river, mature trees, etc.
-Set in a nice metro park. I could see myself visiting the park regularly if I lived in Hays, even if it weren't to play disc golf... except for:

-The course smells like manure. I don't know where it came from; I saw some buffalo herding near the first couple holes, but the smell was most pungent further afield.
-The signage is nonexistent. There are points in the course where a first-timer at Frontier Park would have absolutely no idea where the next tee is. In fact, there were many times I just guessed which tee was next, then found out I was completely wrong based on seeing the pair throwing a couple holes ahead of me. Each tee is marked with a stone, waist-high post, which is aesthetically pleasing in a way, but blends in way too easily with the surroundings.
-The course layout is problematic at best and dangerous at worst. There are too many holes that border the road in such a way that even a seasoned disc golfer could easily hit a passing car without meaning too. Also, there are places, although not many, where the next tee is less than five feet from the previous hole's basket, which seemingly contradicts my last grievance, but the confusion is mixed at Frontier Park.
-When I played the course there was a baseball team practicing in the stadium near holes 7-9, and they were playing top 40 EXTREMELY loud over the speakers. While this is a situational complaint, I'm sure it's not the only time it's happened. If I were a regular here it would drive me insane.

It's frustrating; this course could be fantastic if, minimally, effort would be put into adding signs to each tee indicating which hole it is and where the next tee will be. And if something could be done about that manure...
