Pros:
Very, vey challenging, you'll need a mixed bag of throws. Lots of alternate pin placements that routinely change. Homeless guy that looks like Willie Nelson lives around the 11th hole (no joke) and gathers lost discs. He's cool; he knows a lot about the course and will point out where to go if you're lost.
Cons:
The crowds are one thing, but when groups play the course out of order it throws things way off kilter, especially around the hole 6-hole 7 area. After hole six you can either go straight to hole 7 or the first of the alternate holes. It never fails that as soon as my group finishes hole 6, this large group comes out of the woods right in front of us and to get ready to play hole 7. Often times we've had to skip the hole altogether and replay either hole 1 or 10 (next to the parking lot) to make a full 18.
Some of the regulars can be complete assholes, in part because of the problem listed above, and partly because some of them don't like it at all when you ask to play through.
Some of the tee boxes need work. All the tee signs need replacing, except maybe hole 14.
The basket for hole 13 borders on the fairway at hole 14. Errant throws from the 14 tee come down on 13 all the time.
There's a large field where hole 3, 4, 9, 10, and 18 kind of converge. 18 is supposed to be the main hole but you're right next to the 4 tee, the players at 3 are coming towards you on the left, the tee at 10 is to the right down the fairway, and guys throwing at hole 9 could possibly get in the way depending on where the pin is. More often than not there's no real danger of hitting anybody/getting hit, but it does get really congested in that field sometimes.
Other Thoughts:
For as many cons as I listed, it's not a terrible course. After a while you kind of learn the ways of Seven Oaks and just deal. It's the challenge the course delivers that keeps me coming back. If it weren't as difficult as it is, I probably wouldn't go there so often.
