Pros:
As the last reviewer stated, the course truly is picturesque. After pulling up and parking you find yourself walking into a field that completely opens up with a great view of Lake Isabella and the Olympics. Because this state park is off the beaten path a bit, nature and wildlife is quite abundant. There are several trees on the course but they tend to follow the boundary lines along the property rather then growing directly in the middle. However, with the tournament layout the locals do a great job incorporating the entire land and include some wonderful elevation shots.
There is ample parking for disc golfers and dog walkers alike, although when a tournament is going on you might find yourself parking quite a ways down the road and walking in. There is a kiosk providing disc golfers and park users info as to what is going around locally, a bathroom on site, as well as a few park tables for those who might want to picnic. Apparently, there is also a whole lot of room on the other side of the park (across the street) as well where many can enjoy walking trails and the occasional temp course layout.
I too had the privilege of playing the local temp course which is used for their bigger tournaments and weekly fundraisers so when I played there were baskets! Because it was a tournament, the layout was completely different (going counter clockwise rather then clockwise). This turned the course from being completely right handed bias to more of a lefty friendly course (which was great). I have had several years to perfect my hyzer shot so I was happy to see that I would not be throwing the same shot all day long like their tone course is designed for. Instead, I found myself throwing a lot of anhyzer and side armed shots as well as several low straight tunnel shots. As I stated earlier, elevation did come into play on several shots (although fairly open), although it did have a few pins that were heavily guarded or had some obstacles blocking any direct lines to the pin. Multiple tee pads were great too, as the same layout of the nine holes would get old real quick. Also, if you print out some maps for the tone course there are four unique layouts to keep things fresh for those who play here often.
Cons:
There currently are no signs or baskets and the tee pads are natural. Although natural tee pads don't bother me much usually, the northwest is a tough place to play at times and the tee pads can become very slick or worse, muddy. Also, the bathrooms can get quite ripe at times as there are a lot of park users around and yet I am not sure the bathroom is cleaned regularly so just beware!
Other Thoughts:
If some of the cons were addressed (which I am sure they will) this course would quickly move up as far as its rating to perhaps a 3-3.5 and if more holes were added maybe even a 4. This course truly has a lot of potential and the local club (MCDG) is awesome. Not only are they really friendly but also awesome promoters for the sport. Talks of a new 18/27 hole course has already been approved on a near bye 50 acre piece of land giving Shelton two courses in the area. This will help make Shelton a destination area as long as they continue to make improvements. Although the obstacle course is nowhere near as fun as the temp course, it is still worth it to get out to Shelton to play one of the best obstacle courses around the state of Washington.
