Pros:
For being a pretty small park, this is solid design. The trees are used well, and several of the holes have multiple lanes to the basket. Hole 2 has an outfield scoreboard you need to negotiate if you are throwing a really wide hyzer. Holes 3-9 all have trees somewhere near the basket.
Holes are mostly in the 200-300 range (maybe all of them are), so there are a lot of birdie opportunities. I think I got 5.
Navigation wasn't bad since I was mostly following other players, but the park is small enough that you can probably figure it out.
The Cascades are in the background, so this was a pretty place to play at sunset.
Cons:
The concrete pads are all circular for some reason and aren't quite long enough for a full run up.
There isn't a ton of length here.
Other park users could come into play, although the course does not have any unsafe features design-wise. A pretty bad throw could end up in the baseball fields or on the road.
Other Thoughts:
I was in town to visit North Cascades National Park. I'm surprised how many people there were on a weeknight for a small town. There is clearly support behind this course.
