We bought a hot plate from Fred Meyer (about $13) and used that to cook on since there were utility hook ups. That worked out well and I think was much easier than trying to cook over the fire. Of course we did do smores over the fire.
Of course the weather didn't cooperate. The day we arrived was gorgeous, but it rained quite a bit the second day. It was cloudy the day we left. But we still went out and walked along the river and went out to the beach. Floyd and I ran on the hiking trail (Steam Donkey Trail/Maple Valley Loop) that was at the campground. It was a pretty good run; I think about 4-4.5 miles. I had to walk on the bit that had some switchbacks, but other than that it was fairly good for running. We saw the elk herd and that was pretty cool.
It rained when we went out to the beach, but apparently it is the best spot in Washington to get clams and oysters. We didn't attempt to get any, but we did have fun watching all the little crabs scamper around.
We took the Kingston ferry and the campground was only about an hour off the ferry, so that was nice that it wasn't too far away. Allie doesn't appreciate long car rides.
We got ice cream at Mora in Kingston. As a snobby ice cream eater, their stuff is "homemade" and thus good. I still prefer my own, but theirs is quite comparable.
