Pros:
Unlikely to see anyone else playing
Get to play through some nice woods
Cons:
Pathways are ridiculously narrow, so a safe landing zone is very hard to hit.
Thick underbrush means lost discs are very likely, and you have to tramp through bushes, grass, decaying logs, and spiky things to retrieve almost every shot.
No signage at all. Luckily I found someone to ask where the course started. I had no idea where the tee boxes were supposed to be.
Other Thoughts:
Play with someone else, so you can act as spotters for each other. I spent half my time tramping around looking for my disc, and I lost a disc when I thought I knew exactly where it landed.
