Pros:
Kanza is about what you would expect from Kansas. Good use of elevation and trees, though there's not much of either, and great upkeep overall. The front and back nines are divided by a bike trail, and you're never far from the start.
I didn't expect there to be any par 4's and 5's, but there were. It's a par 60 layout, and the higher pars are real interesting. They make the park a bit cramped at times, but I think it's worth it. Hole 14, the par 5, plays through a tight section, using the creek as OB to make the middle part harder. Hole 17 is overall the best hole on the course, although it plays a little too near one of the paths.
The creek is used on a few other holes to make you think twice on a handful of drives. It ends up making a decent OB challenge. And it's small enough that you can ignore it completely if you want.
While a lot of holes don't have much going for them, they're all a good bit different. That one tree that's in the way is in a slightly different position on almost every hole, and there are a few low ceiling shots at the beginning and end of the course.
Cons:
With the little amount of space there is here, a few holes end up rather boring. Hole 6 is the worst one, but a lot of others have only one tree in the way, and won't provide much difficulty after a few plays through. The drives of 4, 9 and 16, and upshots of 13 and 16 are also pretty wide open. Once you figure out all of this, some of the holes just lose their spiciness.
Even on the more interesting holes, there's often one line that is super open. Granted, which line that is does vary from hole to hole, but when you can step up to several of the tees and throw your most comfortable shot with nothing in the way, it's not great.
The walking and biking paths are really close on some holes. Hole 17 is between two of them, and hole 1 is between one and the parking lot. Playing OB, it makes those fairly interesting holes, but it does hurt safety. A few other holes start right by the path, so while it's easy to see anyone approaching, you might be waiting for a little while. In addition, a few holes play pretty close to each other. When you're already avoiding the paths and the creek, your only option is to throw down the middle, and if you miss that line even by a little, you might be yelling fore.
Other Thoughts:
This does seem like it's a good beginner course. The distance on some of the holes won't be accessible for them, but with the relative openness (but not completely open) and the niceness of the park, this is a decent place. Some shorter tees on the par 4's and 5 would help for beginners.
There aren't many other ways for this course to improve. I think a better version of hole 14 is possible, but I don't know how that would happen. Anything to get hole 6 out would be good, but I again don't know how that would happen.
This feels like the most average course there is. Not bad by any means, but nothing special either. And not just in overall quality, but every aspect is average. But when everything is average, the result ends up being pretty decent, and someplace that most everyone can have fun at.
