Pros:
Tees are clearly defined, which includes pro tees. Well marked holes, easy to follow along. Good elevation changes, with a number of challenging holes. Our group of four played for three hours with not a soul on the property (including the course owner). Good mix of wooded and wide open shots, though most are fairly wooded. Very big course, as despite the vast number of trees, you still have plenty of room to throw. Baskets are all in good shape.
Cons:
Dirt tees only, despite being clearly marked. Terrain is fairly treacherous, so be sure to wear good shoes. Somewhat in the middle of nowhere, might be easy to miss from the road (watch for the big Innova banner, though).
Other Thoughts:
You can tell that the guy who runs this course is working hard on it. There is some room for improvement just to clean the course up, but it is very fun to play. There's an honor box on the grounds, with $5 per person for all-day play, and I believe $3 for just a round. I was glad to spend the $5 on this course, as I had a lot of fun playing it. There is a "pro shop" on the grounds, but the owner was not present when we played. If you're anywhere near Crandon, you should go out of your way to give this place a shot. Odds are you won't have much company there, so give it a shot. Be sure to bring a spotter - very easy to lose a disc in the woods.
