Pros:
Holes 1-8 vary in elevation and most have foilage.
Some have Water Hazards that are very fun to play.
Each hole has cement tee boxes and a sign telling par and distance, along with direction the hole is in (very helpful going up hills.) Great baskets.
The park is very scenic, and nature is all over. Last time I went, a fox walked within 25ft of me.
Lots of animals, a great shelter, 3 softball diamonds, and a couple good playgrounds. Good parking lot.
The first 8 holes are the funnest to play, specifically hole 5. Hole 5, in my opinion, is the best hole in Illinois. That hole alone is enough to go to the course, the other 17 holes add to that.
Cons:
Holes 9-18 are rather boring, as you are just going across the flatness of Illinois.
Also, You have to make a decent walk if you want to go from 18 back to 1.
The park is often crowded.
In the front 9, its pretty easy to turn an errant throw into a missing disc, due to the poison ivy and stinging nettles, heavy wooded areas and steep, loos dirt hills.
Other than that, theres not much bad to say.
Other Thoughts:
Best home course ever? yes, yes it is.
