Pros:
Just a gorgeous course, both in terms of how well maintained it is and the mountain setting.
Good variety of shots, with tons of mid-range shaping and scrambling opportunities. You will be well rewarded if you can throw both backhand and forehand.
Very fair for newer and average skilled players, with several good birdie opportunities.
Lots of elevation change on the course, which makes for several cool uphill or downhill holes.
Cons:
Almost entirely a par 3 course (there is one par 4), so very little chance to really air out your drivers.
Woods are deep enough that losing a disc is very possible, especially if you play solo or without a spotter.
Short playing season due to snow.
Other Thoughts:
While the Upper course gets more love, and is much more challenging, the Lower course is an awful lot of fun.
Extremely well maintained, with mowed fairways that clearly define where you want to throw.
Really nice concrete tee pads.
