Pros:
-Baskets are visible on approach to the hole and/or from the tee
-Most fairways are good but... (see bullet 3 in cons section)
-Elevation is used really really well, hole 18 is a massive downhill, so massive in fact that you can expect to lose a disc. (This is a pro and a con)
-This is a mostly wooded course where trees come into play often, they make it challenging, but not too hard.
-Terrace Creek Park is a really pretty park
-Lots of options in terms of what to throw, many creative lines, as well as a few traditional ones
Cons:
-Tees are too small, and sometimes awkward to get on if they are on a hill
-There was one tee sign (#7) and it was covered in graffiti
-Hole 11's fairway is a concrete running path which has many runners on it, hole 9 you have the option of concrete path, or a swamp.
-Disc Golf Paths are awful, running Paths are decent. Hole 18's path is basically a dried out waterfall, bring your butt padding.
-Navigation is impossible without a map, and very difficult with a map, No Tee signs + haphazard layout + unclear markings on Baskets=impossible
-Only a few benches, many of which are rotten wood
-Many fairways intersect, or end within 20 feet of the next tee. Fairways also cross running paths (or are running Paths) frequently.
-This course gets a 1/4 on the New Shoe Index, Of someone can play this course without getting mud all over their shoes I will buy them dinner.
(Not actually but you get the idea)
-Holes 1-4 are completely separate from the rest of the course, also hole 18 to parking lot is a really long walk, the course doesn't loop around at all.
Other Thoughts:
If you are tired of playing the same old courses, give this one a try, it is nice and close to Seattle. However, don't go out of your way.
