Pros:
This course is very accessible. Take exit 52 and drive west about 100', and you're there. I've always wanted a place to stretch my legs on the drive between PDX and Seattle, and I've finally found it.
The baskets are in great condition and catch well, and the course is reasonably well designed. Ignoring the length of the holes, I have to say that there are some creative lines here. You have hyzers, anhyzers, and as much elevation change as the land will allow. Notable shots are hole 6 from the wooden platform and hole 8 from the entrance. Hole 5 was memorable too, but that's because I dropped a thumber into the bed of a pickup truck.
I don't often go to disc golf courses for anything but disc golf. In fact, I never go to disc golf courses for anything but disc golf. But the other activities here are definitely worth bringing the family for. Paddleball, giant croquet, badminton, a playground...
Cons:
The challenge just isn't here. I'm not a good player by any stretch, and I was still bored by the end of the course. Holes 5 and 6 were okay with a tight window and a low ceiling respectively. Any semi-serious player will be bored before they're halfway done though. Grab a putter and maybe a mid and you should be good here.
I feel like this next one is a con on waaay too many courses: The teepads are awful. They're well marked, but any time that a tee is non-existent it's going to get worn in, pitted, and treacherous. This course obviously won't get a ton of traffic, but I did hook at least one drive because I was concerned about my footing.
It was pretty easy to navigate here, but a map of some sort would be helpful for the target audience. A family walking up with a Frisbee that they found in the woods probably won't even figure out where tee 1 is.
The other activities at the park can get in the way, with the croquet field being in play on hole 2 and what I'm assuming used to be the BMX track following that. Hole 9 is the only one I would truly call a con though. The basket is placed far too close to a playground, which is an accident just waiting to happen.
Other Thoughts:
This course is great for the crowd that it's designed for: Beginners and rec players. I hadn't officially introduced my girlfriend to this addiction yet, and it was a perfect place to hand her a Gazelle and a Fuse and watch her catch the bug. But if I'm reviewing this against a lot of the other courses that I've reviewed, I can't give it a good rating. Definitely worth a stop for the accessibility, but not anywhere close to being a destination.
