Pros:
Signs, tees, and baskets. For a very highly skilled player, some really tough lines.
Cons:
Many places where it would be next to impossible to land safely on the preferred line, with no safe place to lay up.
Other Thoughts:
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.
