Pros:
Rare that I would give a nine hole course a 3 rating. As mentioned in other reviews, this one is a gem. Except for hole #1, I consider all holes a tough deuce. #1, #4 and #5 are possible twos. However, my companion and I both were in the road next to #4, and considered this out of bounds. Other reviews stated river is not in play on water hole. I disagree, as to get close to bucket requires going over river the entire way. I was in both times, with one lost disc. We were mopping up small courses we had not played in Wisconsin as well as a number of courses a little west of Chicago. We knew there were not many great courses along our route. With that said, Fireman's Park, Waterloo, beat out a number of Illinois 18's and was our favorite course of trip. We played 18 total courses. In other words, this one is pretty darn good....
Cons:
To get to hole #1 from 9 requires a walk. We played #7 a second time each round to return to beginning. #7 is a nice hole, and so, was no big deal.
Other Thoughts:
Am interested in trying alt. 9 next time I get out there; which I plan to do. Combine this course with the course at Watertown; which has recently added a very good back nine and I think you will have added a couple of hidden gems to your list..
