You really can't talk about Washington state parks and compare them to NP,NFS or corp of engineer parks cuz that's apples and oranges. Most state parks have w/e or full h/u at most sites and most are large enuff for large rigs. Try getting most of our rigs in the other public run parks and in my experience, once you get out of the PNW, the state parks are not evenboon dock standards and you have to stay at Private parks to get decent sites.
