Pros:
The oldest course in the state continues to impress with its perfect preservation, providing a powerful first peek to any players who pace onto its property and pursue its premises. The tees and signs look good, the baskets don't have any rust, and there's plenty of parking. With the river to one side, there's a good bit of scenery, especially if there's some mist in the air.
Most holes classify as moderately wooded, and they're all pretty solid. There are opportunities for wide hyzers, low ceiling shots, and even some rollers. The raised pin on 1 is a nice touch, though I might have preferred that on a different hole.
While there aren't any hilly holes, there are a few holes that play slightly downhill, and those are pretty cool. They give a chance to get a little more distance off the tee, but don't make the hole gimmicky at all.
This course features a lot of holes that will make you want to finish left or right, even if they aren't complete doglegs. There's the baseball shot on 2, and then several long pins will have some sort of spicy finish around a tree. Even if you have multiple options, this course emphasizes shot shaping at a fairly long distance. But newer players can also just chuck whatever and still get to the basket eventually.
The many pin placements here are used pretty well. They vary the distance quite a bit, but they all seem to focus on accuracy in the 300 foot range, so if you're born with that ability, you're in luck.
Cons:
There's almost no elevation change. Only a few holes play even slightly up or down, and while some holes don't need it, elevation would make the easy holes a lot more interesting. Holes 11-14 are all pretty short, and a lot of the short pins stand to be fairly boring as well.
While I would have liked a few more par 4's, the ones there are don't fit in with the course very well. They take up a lot of space in a park that doesn't have much real estate to work with, and on most of them, there isn't any kind of landing zone. It kind of feels like a few holes, or potential holes, are ruined by extra space given to some rather uninteresting par 4's.
Even with the good holes, a lot of them are just about the same: throw it straight for 300-400 feet, then finish right or left. It starts to get a little boring, which is why adding more, or possibly fewer, par 4's could help a bit to give a little more variety. It seems like the variety of the course comes in the different pin positions, which is fine, but probably isn't ideal, especially when you're sacrificing other aspects of the course.
Holes 16-18 are not a good way to finish the course. They're across the parking lot from the rest of the course, and they're just not very good, playing over several roads or sidewalks, causing some backtracking, and just being rather uninteresting. Actually, a few other holes play near some sidewalks, and you don't want to venture across them on holes 10 and 12, where weeds and the river await.
Other Thoughts:
It would be nice if all 18 holes could be on the same side of the park, but it would make the course even more squished than it already is.
It would also involve splitting holes 4 and 15 in two, and that result would be lousy at best.
It is technically possible to end up in the water on hole 1, because of course it is if you're in Topeka.
Overall, this is a fairly average course, but it doesn't do anything exceptionally bad. It has stood the test of time and looks to be here to stay.
