Yelm, WA camp spots

There is the Red Wind Casino about 5 miles south of Yelm, and I think they allow parking, but the closest one is in Nisqually http://www.rvparkreviews.com/regions/washington/olympia/nisqually-plaza-rv-park but I don't know anything about it except what I read here.
Fort Lewis if your military and there is a small one in the town of Tenino which is about 15 miles or so down the road. Millersylvania is the closest State Park and I think if you belong to the Legion they have a parking lot in Yelm that allows RVs. Pickin's are kind of slim unfortunately

None in Yelm, but quite a number in the Lacy, Nisqually and Dupot area.
