Pros:
-McNaughton Park has a section of the park that's used exclusively for disc golf, and it's fantastic!
-Even though some of the holes fairways are very close to each other, each and every hole has it's own little secluded feeling.
-It's very challenging. I had a very hard time landing on the fairway on several of the holes. There's a great mix of shots here, whether it's uphill/downhill, wooded/open, hyzer/anhyzer, this park has it all!
-Very easy to find, fairly clean, scenic, and best of all, free!
-Although we could hear people on the course yelling or swearing or cheering, we never actually saw anyone because of the foresty terrain. It was really nice.
Cons:
-The tees really, really, really need maps. Playing for the first time, I had no idea where I was going and had to follow the group in front of me. Some of the yellow arrows on the DGA baskets were pointing the wrong way and it really threw me off.
-#17 and #18 are, in my opinion, useless. You have to cross the road, then cross over 18's fairway, and then walk another 400 feet to get to 17's tee. And then you have to go uphill to get to 18 and then you go back downhill and then back uphill to get to your car. I just skipped the last two because they just didn't seem worth it to me.
Other Thoughts:
While I don't think that this the best course in IL, I think it's definitely in the top 10. This course, as I said, did a fantastic job of challenging me with many different shots. Some of the fairways were 10-15 wide so it's very difficult to have solid drives on many of the holes. Good luck!
