Pros:
The course plays through a sprawling park with a nice mix of grassy fairways and tighter wooded shots. The woods come into play even on most of the more open holes, and offer some good punishment for errant drives. Most holes have some elevation changes adding challenge and variety, including some nice ravine holes in the woods and some cool roll away greens.
There is a pretty good mix of hole shapes, playing pretty balanced for righties and lefties. You'll need to hit some tight lines through the woods to score well, and there's enough different shots required to keep it from feeling repetitive. The concrete pads are in pretty good shape, and there are two longer sets of tees on most holes that add some different lines and more distance. There are basic tee signs, and the course isn't too tough to follow and figure out. The tee to the practice basket is a nice way to get from the parking lot to hole 1's tee and eliminate that long walk.
Cons:
The concretes play very short and pretty easy overall, lots of ace runs and deuce or die type holes out there. The longer tees are more interesting and challenging, but aren't all easy to find or well marked, and many of them are in pretty poor shape with ruts and erosion. There are also erosion problems on some of the hills in the woods where not much grass can grow. There is a long walk back from the end of the course to the parking lot, not a huge deal but a little annoying.
Other Thoughts:
This is a fun course, with lots of fun ace runs and elevation shots. Beginners will find the woods a little tight at times, but it's a pretty approachable course. More experienced players won't find the concretes very tough at all, and the longer tees aren't always all that easy to find and throw from. There were some guys out working on a couple of them though, some improvements on those would really bump up the level of this course. There are better courses around St. Louis, but this one is still worth a stop.
