Pros:
The course is in a small park with some minor elevation changes, and scattered trees and brush. There are some areas of the park with denser clusters of trees, and the course makes good use of these to add some challenge. Though the elevation changes are limited, most of the holes play up or down at least a small hill. None of the holes were completely wide open and simple, setting this course apart from the design of many other Chicago courses.
There was good length variety here. There were some ace run holes, a longer hole that lets you drive if you can get through or over the trees, and holes in between that offer a chance for an ace for experienced players and are reasonable for newer players.
There are great concrete tee pads on all the holes, that are very large and in really nice shape. The hole signs are in good shape, and show the hole layout with the distance. The course is extremely easy to follow, with no navigation issues at all.
I was pleasantly surprised by the design of this course. It's a small multi-use park, but the course doesn't really play into the other areas of the park, and only one of the holes endangers the walking paths throughout the park. There is more challenge here than it first appears.
Cons:
The biggest issue on this course is the traffic it gets by non-players and inexperienced players with no sense of course etiquette. There were many people wandering around on the course rather than staying on the walking paths. They seemed to be oblivious to the course, and weren't interested in paying attention when asked to move or at least watch while you throw. The other players on the course were mostly people with one disc who wanted to throw on you on every hole but refused to play through.
The walking path is in a dangerous spot on the second hole, and makes for some waiting if there are walkers out. There are a couple playgrounds that aren't really in play, but could be with particularly bad throws. The third hole plays around the corner of a restricted area, looks like an easy way to lose a disc.
Other Thoughts:
This is a great beginner course. The lengths are reasonable, but the holes aren't just wide open. There aren't many places to lose a disc. More experienced players will be surprised at some of the challenges on this course, and will likely have a fun quick round here.
This is one of my favorite Chicago 9 holers, and it's definitely worth a stop if you're in the area. Don't drive way out of your way for just this course, but there are some other fun places to play in the area that make it worth a look.
