There happen to be quite a few campgrounds in the region, with one about a quarter of a mile upstream from where this picture was taken, and another less than three miles past that. Both are primarily used by school age children. The vast redwood forests with creeks flowing through are ideal for such campgrounds.
This is a campground too. I know it does not look like it. It is located between a creek and an industrial building, the eave of which is visible in the top right corner of the picture. The herd of dumpsters that is barely visible at the bottom of the picture might include a dozen dumpsters at at time. (I tried to get both the eave and the dumpsters in one picture.) There really are two rows of barbed wire on top of that fence behind the dumpsters.
Nonetheless, it is a campground. You see…
