I just bought a copy of Ray's Guides: Free Camping Oregon Campgrounds

Here's a representative listing (I think we're going to visit this one):
Oregon Mine Campground
From Mt Vernon, travel west on US Highway 26 for about 10 and take a left onto Forest Service Road 21, the Fields Creek Road. Follow Forest Service Road 21 to Forest Service Road 2170, take a right and continue on to the forest Camp. Oregon Mine Campground offers 5 camp sites with tables, fire rings, toilet and a buck and pole corral. A beautiful setting with big yellow pine, adjacent to a stream for fishing. Stock water is available in the adjacent Murderer's Creek. Be aware that wild horses roam in this area. 4300 foot elevation.
Ray's a nice guy. Many of his listings say that the site will accommodate a small trailer. I emailed and asked if thought a 25 footer would fit in most of them and he wrote back to inform me that it should be OK.
I like the idea of these campsites. Not disbursed camping but small campgrounds. Most have fewer than 10 sites and have fire rings and tables. Sometimes a potty, sometimes not. Same with water. There are hundreds of these campgrounds scattered around the Great State of Oregon (I love this state). Ray also has guides to Washington and Idaho.
One question to any horse campers out there... There are a lot of horse camps with corrals and such. Do you think it's OK to camp in these without horses? I hate to displace someone with horses as they don't have as many campground choices as we do.
See you on the trail.
