Pros:
18 holes set up in Winnebago County Park, with plenty of parking, and easy to find.
DGA Mach 3 baskets, which were all in good shape and caught as well as you'd expect. Only one pin position per hole. Each number sign on top of the basket had a "next tee" arrow, which really helps with navigation.
Concrete tee pads, all very grippy, and in solid condition. Plenty long enough, and good texture on most.
Good tee signs at each hole, showing distance, par, intended line, and any possible OB. Very nice, easy to read, with all the info you could need.
This is not a course for noodle arms. Coming in at an average of 385' per hole, you'll be pulling back and bombing quite a bit. I like it, as there's not a ton of courses in the area with a lot of "let 'er rip" type holes. It fills a decent niche, IMO.
There are some fun holes here, as well. 5 and 6 both offer fun turnover lines. 9, 10, and 11 add some nice elevation changes in the form of a big mound. 13 plays 390ish feet along a river (don't go in here...it's kind of yuck). 16 is fantastic, IMO. 629', with the fairway running along the edge of a large pond. A super cool hole. 18 is something you don't see a ton of, a long, right turning fairway. All in all, some decent designs here.
Cons:
This course can get a big monotonous at times. Lots of longer holes with almost no obstacles really mar what could have been a great course. I don't mind a few holes where you get to just pull back and air it out, but there's just a few too many here.
The back 9 is rife with prairie grass. We played it before the grass was tall, so it wasn't really an issue, but I can't imagine it's fun to play here in late summer with the wind blowing.
There's a few long walks between holes, and the Green and Yellow courses play close to each other over holes 3 and 4.
Other Thoughts:
All in all, this is a decent course, and is helped by the fact that it somewhat stands alone in the area for what it is...a long, open-ish course. For me (a person throwing 360-390, usually), it was pretty fun, as there were a few holes that played to my max distance. For shorter throwers, it's going to be pretty boring, I would think. A lot of drive/upshot/putt.
I probably won't go out of my way to play it too often, especially with so many great courses in the area. In fact, if I was in a group, I'd probably prefer the Green course. You could definitely do worse, though. Just make sure to get out there before the grass gets too long!
