Pros:
It's free... I liked the layout. Great variety between holes. Makes great use of the terrain.
Cons:
Hardly any markings at all... If you've never seen a pole hole before you wouldn't know that it was a disc golf course. Each hole has a white post with the hole number on it but that's it. No distances, pars or hole layouts. On several holes you have to hunt for the target before teeing off. And when you hole out, you have to hunt for the next tee. Tee pads are small and don't allow for a good run up.
Other Thoughts:
With some superficial improvements the rating could go way up.
