Pros:
Prairie Center is one of the oldest courses in Kansas City, home of the first Kansas City Wide Open, and has happily stood the test of time by remaining a quality course despite so much else changing. The tee pads, baskets, parking, and signs are all in at least decent shape, and there's potential for a fun round for nearly all players. Maintenance is pristine. There's also bathrooms and plenty of parking.
The best part of this course is the variance: no two holes are the same. Some of the unique ones are throwing over or through a line of trees on 10, the water on 15, over the tree farm on 9, and more. The island shot on 2 or 4 (usually 2) is also fantastic; it's difficult to go for it off the tee, but it's fun landing near the road and putting over OB to a basket that really isn't far away. I also enjoy the tunnel shots on 3 and 6.
The newer holes, 11-14, are absolutely fantastic. Other than 11 being between two sports fields, it's a really difficult hole that takes some playing to get used to. Holes 12 and 13 (in longer pins) are epic par 4's that involve weaving through lots of trees, and placement of your first shot is crucial. They're all possible to birdie, but very difficult. After those, it's hole 14, which is still in the woods but has room to air it out.
The rest of the course plays like a casual park-style course, except there is some challenge at every turn, whether it be a tree to hit early (6-10, 18), some wind (17 is windy for some reason), or an OB path or road (2, 3, 16, 17).
Even if some holes are a bit tweener, there's still incentive to throw your drive as far as possible, but there will almost always be trees ready to knock you down. There's are individual trees in the middle of the fairways of 6 and 11, that really should be easy to avoid, but certainly gets in your head and have probably caused many shots to go awry. On holes like 7 and 18, most players will have no hope of a birdie, but the farther the drive goes, the easier the upshot will be. In addition, a long tee shot that ends up left or right is still okay. This isn't always good (and certainly isn't the case on 13 and 14), but for a few holes it's good.
Cons:
Not much elevation change. There's enough for some decent variety on several holes, but it isn't enough to give the course enough variety to complement the variety in wooded-ness and shot shapes. Most holes have a little elevation change, but there are no steep slopes to be seen. It makes certain sets of holes quite similar - not the same, but rather similar.
Several holes don't feel very normal. There's not really a good line on 6, 7, or 18, and as like many traditional holes, everything is just blindly labeled as par 3, despite several being rather tweener holes. I also don't like hole 15, the water shot, mostly because the bailout option to the right leaves you in a pretty terrible spot to try to get a par. A few holes have lines over the top of all the trees, on some of the holes that have a slightly elevated tee pad.
There are several holes with two tee pads, but they don't add much to the course. I usually play the longs, but I'm pretty sure the short tee is intended to be used on 8, and the tee pad you use on 15 is dictated by which pin is in use. On the others, holes 2, 6, and 18, both tee pads are close enough together that they don't change the hole much.
The park is often quite busy. There aren't usually non-discers on the fairways, but the sports fields nearby can be issues. Holes 11 and 17 play beside a baseball field, and 11 and 14 are also near a soccer field. In addition to a lot of noise, you'd better be confident you won't be disturbing some soccer moms on the edge of the field.
Other Thoughts:
I wish this course could utilize some more of the woods around hole 13. It would add a few more wooded holes, and they wouldn't have to be long. It would also allow some of the holes in the 5-8 area to be a bit more spread out. Other than that, this course really doesn't have any true weak points that would be easy to fix. It's possible that the tee pads or signs will soon become worn out and be in need of replacement, but they're in good shape right now. There are also a couple of holes that would lose their charm if one tree fell down.
There's some housing being build behind the baskets of 11 and adjacent to the fairway of 12. It shouldn't disturb the course at all, but all it would take is one or two backyards to become a little bigger than they ought and those holes would be toast.
Overall, this is a pretty fun course that has quite a bit to be excited about, but it's issues still prevent it from getting a higher rating from me, and it has been upstaged by lots of other courses in the area. But if you want to see where a big part of Disc Golf in Kansas City started, then this is the place to go. Nearly all skill levels can have fun here (though some may need to skip 15) and experience the history of this park and how it has remained a quality course.
