I've got a different version of camp spreading.
It was at a USFS campground. The people pulled into the site. Immediately, they got out a pole saw and started cutting branches off trees. Then they got out a weed wacker and started mowing down vegetation that wasn't tree sized. I'm not talking just grass, but vegetation that was waist to shoulder height. Probably doubled the open area of the camp site. This was a forested campground with lots of vegetation between sites (which we prefer so as not to be a big open area). Of course, there was a site and trailer for a campground host, but he/she was not there the entire time we stayed at the campground.
The camper must have been somewhat local, because he came back and started unloading firewood at his site and stacking it between trees. He probably had a full rick of wood stacked up before he was done. Fortunately, we were leaving the next day, so we didn't have to contend with whatever other modifications or actions he took on.
