Pros:
The course plays in a hilly park around two large ponds. There is significant elevation change on a few of the holes, making for a nice change from the usual flat Chicago courses. The park is filled with tall prairie grass, but there are nicely mowed fairways for all the holes. Because of the elevation, and the severe drop offs to the ponds, the wind does very interesting things as it swirls through the course, making every shot a challenge to figure out how to use the wind and not get blown off into the rough.
There is a good variety of lengths on the course, from ace run holes, to holes that are long enough to let a drive rip. No matter the length, this course really favors shot placement, as the rough is very tall thick grass that eats discs. Most of the holes don't force a single line, and are fair to right or left handed players.
There are nice signs for every hole, though they are all about 8 feet up in the air on tall poles for some reason. The tees are pavers with wood frames, and offer fine footing to tee from. There is a good course map at the parking lot, but you won't need it as the course flows well and is easy to follow.
It was fun to play in some different scenery than most of the other courses around. The two ponds down in deep holes were very cool, and made for good views and some challenging shots. Errant drives could sail a long way down the hill, and leave you with a tough shot back up the hill.
Cons:
To me, prairie grass gets old quickly. If you don't keep your disc right on the fairway, it will be difficult to find. It's a little frustrating to have to search for a disc that landed 15' from the basket, let alone how difficult it would be to find one that went really wild.
The tees were nice pavers, but were tiny and didn't give nearly enough space. They weren't quite flush with the ground, so it was a little frustrating to try either to do a short run up, or to have to step up on to the tee in the middle.
There were a lot of casual players, and many of them lost their one disc on just about every hole. This means that the groups of 6 can take a full 10 minutes to play the hole, and are spread out across the fairways of a couple holes making it impossible to play through. We were constantly thrown on by groups behind us, even after friendly conversations about etiquette. The course ends right by the tee for hole 4, and it seems that a lot of the casual players don't feel like walking over the hill to the first tee, instead they jump in right in the middle of the course backing things up even more.
Though the elevation and wind are fun obstacles, this course doesn't force any line shaping skills. You can throw every hole pretty much however you want, and still end up either with a great shot or a shot that you'll spend a while looking for.
Other Thoughts:
I was surprised at how many beginners were out on this course. There are some longer holes, lots of elevation and wind, and it's very easy to lose a disc if you don't have good control. More experienced players will have fun with the challenges here, but there's not enough to bring an experienced player back to the course very many times. If there were more trees, this could be a more interesting course that would test more parts of your game.
This is definitely a different course than any of the others around, and so it's worth checking out if you're in the area. Don't drive too far out of your way just for this course, but if you do come bring your brightly colored discs and a spotter if you can.
