Pros:
As others have said, absolutely the cleanest DG course/park I've ever seen.
All concrete tee pads, plenty of length and in great shape. Discatcher baskets in very good condition. Tee signs are all present and very nicely done. Course map PDF file is also very nice. Bathrooms as well as other typical park facilities are present an in nice shape.
Some open flat holes where you can really let it rip, nice for stretching out your arm. Also it's always nice to see several holes you can pick up a deuce with if your drive is true.
Course has double loop pattern for both nines, that start and end in a common area, well thought out layout.
Can be played pretty quickly if you need to since it is in a very compact area, and there is not much terrain or vegetation to slow you down. Looks like it could get pretty busy during peak use.
My memorable holes:
1 - Dead straight let 'er rip. Fun to really let it fly once in a while without trees intimidating you.
3 - Neat anhyzer around the trees, down then back up to the basket on the slope, challenge for a par.
4 - Sadly my only deuce of the day, and certainly not on the easiest hole. Try a hyzer and hope you can get through all the trees to the basket.
8 - I mention this one because I ALMOST aced it. About a foot high and left. Definitely an ace-able hole, not quite as simple as it looks at first, have to use some s-curve to hit chains.
9 - Fun little anhyzer...wait I mean big anhyzer. Or make that a lot of anhyzer on a short hole. If you can park this one I applaud you.
12 - Have to "S" it to get around the big tree. Almost deuced it but my bad putting skills prevailed, sadly.
13 - Long with trees shaping your shot, slightly downhill then back up to the basket on the slope. They say play a pro par of 3, but man I think it's hard to hole out a 3 on this one..
18 - Throw a nice long fading hyzer, and you should be looking at a deuce if you get it right. Nice end to a lovely course.
Cons:
Not really challenging. I am by no means an excellent player, and I only had 3 bogies, and even had a deuce. Not that I hate writing down 2's, but I almost 3'd or better on every hole. But overall good use of the available land.
I don't really care for playing next to a somewhat busy road for hole 12, but it's not too bad, just don't turn your disc over horribly.
Other than that, there really isn't much negative to say about the course.
Other Thoughts:
My rating of a 4 is based on the fact that the course is fun, but really lacks the challenge of a strong course. The fact that it is SO clean and SO accessible (just a couple miles off of I-65) bumps it back up to the 4-disc range.
If you're in Bowling Green, definitely hit this one up if you have the time, and then go visit its sibling down the road a couple miles at Kereiakes Park.
