Signs, tees, and baskets. For a very highly skilled player, some really tough lines.

Many places where it would be next to impossible to land safely on the preferred line, with no safe place to lay up.

Not every course should be made as tough as possible. Toughness was added by making low-chance-of-success shots. Gaps too narrow, landing places too small, too much OB too near the basket, too many blind throws, too many places a disc could be lost.
The best way to save this course would be to adapt it to be the easy course the land allows. That might be a par 2 course.
If you have a non-playing co-worker you can't stand who is always begging you to take him disc golfing, take him here. Tell him all disc golf is like this.

-Good Signs, Score card box and map on first tee (I didn't even check to see if there was cards in there. I was using Udisc for my map, but its fairly easy to follow

-Short tee boxes
-Some baskets are dangerously close to other tee pads
-Water comes into play on almost half of the holes, with tons of branches and tight lanes all it takes is to be a little off and you will be getting wet
-Hole 12 is next to impossible, its over 250' water carry and there are bushes and trees where you need to land that will very easily knock your disc back into the water, I played in late fall so the pond was clear but in the summer I'm sure its coverd in scuzz
-I played in late fall so bugs were a non issue, but being familiar with this area I'm sure bugs can be terrible in the summer, also Little Rock Lake has notorious green alge problem in the summer which smells and looks terrible

I've know about this course since I started playing disc golf, it's 10 minutes from where I grew up and still have family so I've had ample opportunities to play it but I always passed it up because I was waiting for the right time when the creek is froze over but there is little to no snow on the ground. I got impatient and decided to play it in early November before the creek froze on the justification the creek is clear and shallow enough I can get my disc back if I went in. Now that I finally played it to check it off the list I can say it lived up to my non existent expectations and not in a good way. I didnt even finish the course, after hole 14 I had already gone in the creek 4 times, lost one disc when the current took it to a deep part of the creek over 5' deep, I skipped hole 12 because I knew it was guaranteed lost disc, when I saw 15 was over 300' hugging the creek the hole way I skipped that one too and looked at the rest of the holes which also played close to the creek (which is way wider and way deeper than you expect) I threw my hands up and said "I'm good" and walked off the course.
