Pros:
It's been about six years since the last review and a couple of things have changed.
Since the pictures have been posted, a lot of the trees have naturally grown, which is good and bad.
The good is that the fairways are tighter and this course plays a little bit more difficult. I'll address the in the Cons section.
All in all, this is a really fun course for any level player. The holes can all be birdied pretty easily, but if you hit an early tree or totally shank your drive, you can end up fighting for the par save.
I like that there are modest elevation changes and the course still seems to be getting played regularly (based on people writing their aces/dates on the tee sign).
Baskets were in great condition. Course navigation is very intuitive. The walks between holes is very, very short. Rounds here go very quickly. You'll find yourself asking "We're on hole 8 already?".
It plays pretty fair. The more accurate player will win here. It's a course that clearly rewards accuracy and not power.
Cons:
The trees have overgrown a couple of the tees. Speaking of tees, they are quite eroded (dirt tees) and several have roots all over them, making it tricky to get an x-step in. All holes except for one are under 200', so maybe you won't need an x-step. The trees have also grown noticeably, particularly on #2-#4 & #9, making these holes much more difficult than pictured.
There was unfortunately quite a bit of garbage throughout the course.
I can imagine that in late summer and fall, the prairie grass can be quite brutal that surrounds several of the later holes.
Other Thoughts:
All in all, this was certainly a much better 9 holes than the neighborhood course a couple blocks down. I was pretty impressed and had a blast here. It's not really a destination course, by any means, but if you're interested in bagging two courses within a few blocks of each other, Fireman's Park isn't painful.
