I spent one night last September Boysen SP in the lower CG. Seemed a little pricey for non-residents at $7 more. I don't recall mosquitos but the biting flies were bad until it cooled off and the place a bit buggy. They had a few spigots and decent grassy areas. I explored around the dam upstream. There's a railroad on the other side of the river with a few trains but no horns blaring. The year before I passed through the area and stayed on the western side of Boysen at Lake Cameahwait. It was free boondocking. There are several spots on the south side of the lake with pit toilets and you can fit 2-3 campers in a spot. there were nice shelters but what looked like a hoard of barn swallows and just made a mess of them. It was a little buggy until dark. There is a paved road almost all the way there but watch for large potholes.
