Pros:
Private course - not being able to play this course freely makes playing it that much better. Beautiful scenery.
Layout - Tight technical play. Put your drivers away folks, you may only throw three drives in an entire round here. Plenty of birdie opportunities with a well placed mid range shot. Plenty of Double bogie opportunities when an otherwise well placed shot misses its line. A few water hazards to beware of making for some excellent hole layouts (18, over the river!)
Multiple Baskets - It was clear from the extra PVC pipes sticking out of the ground that many of the holes move from time to time. I only played the 1 layout but nice to see that next year it will probably be different.
Cons:
Layout - Bring your hiking boots. This may not be a con for a lot of people, but don't expect an easy walk through this one. Very hilly, very wooded.
Baskets - Old baskets, some rusty, shallow baskets, a few chains don't sit right here or there. Not a huge deal, just something to be aware of when throwing at them.
Benches - None? I don't remember any, and certainly sat on the ground a few times. With the tiring terrain this would be an excellent addition.
Tee boxes - No mats, not that it was a huge problem. Most tees packed smooth dirt, but a fair number had roots/rocks to deal with.
Other Thoughts:
A must play if you ever get the opportunity. Respect the course and don't go without permission.
Watch out for that nasty hill on 1. Rolling down that spells disaster.
Having an overstable mid range will save your life.
