Pros:
This course seriously makes you choose every shot for placement, forcing you to understand how every disk in your bag flies. Not only is there a swamp area that runs adjacent to many holes (or through them) but there is heavy brush and trees, water, and a very uncommon feature in illinois, hills and depressions that will make you lose sight of your disk on an errant throw.
The playing area itself and paths are well maintained, the out of bounds areas are well... out of bounds.
You can tell that they take a lot of time trying to improve the course with landscaping and planting of small trees and shrubs.
Also, there is a red fox that lives on hole 10... i watched it come out and sniff my disc i had just thrown then dart back into its hole.
A cool effect I havent seen anywhere else... from the tee off platform, there is a gravel shaped triangle in front of it, making the tee off platform into an arrow pointed at the basket. Also, on some of the more wooded path holes, the baskets have certain parts of them that are painted red, you follow the red painted section to the path that leads you to the next hole.
Cons:
Many bugs, including the beast sized bees that swarm.
Depending on what time of the day you go, the clientele might make the course less then family friendly.
Other Thoughts:
Honestly my favorite course, challenging yet not too out of reach for the beginner. You may want to wear shoes that you arent afraid to get muddy though, just in case you end up in swamp while looking for the disk that didnt do what you wanted it to.
