Pros:
Technical and challenging wooded course will severely punish an errant throw, but with little chance of actually losing a disc. The danger of the ravine is a bit overstated; if you backtrack far enough you can usually find an easy and safe way down to your disc.
Most of the course is shaded, making it a good choice on a hot summer day.
Pretty scenery, elevation changes, and hundreds of trees to either damn or cheer, depending on where they deflect your disc to. Red, white, and blue tees truly play to their intended level, from an enjoyable jaunt in the park to a maddening sharpshooter's challenge.
Cons:
Young, inconsiderate "Ridge Rats" sometimes frequent the course, and litterbugs abound. More garbage cans would help alleviate the situation.
Teeboxes can be a muddy mess during rainy periods.
The course dearly needs better signage, as almost every new player gets lost trying to find 10 and 13 for the first time.
Other Thoughts:
The Ridge can quickly become an obsession for local players, despite its minor faults. A few inches here, a few inches there can be the difference between an excellent round and an embarrassment. Players who rely on a big distance drive off the tee will be cut down to size here; deadly accuracy and the ability to thow a variety of lines are far more valuable.
