Talk is that camp site fees are being increased. They charge too much already. I prefer finding a nice, secluded spot in a National Forest, but that isn’t always available. And it can be nice to have a bathroom.
In Village Books last week, I happened upon Ray’s Guides: Free Campgrounds in Washington State. The book is a no-nonsense list of free camp sites in the state. I’ve yet to have a chance to check out any of the listed sites, but hope to soon. Ray also has guides for Oregon and Idaho.
