Larson Ridge is easily becoming one of my new favorite campgrounds. The sites are within a 1/4 mile of the highway (close enough to see the vehicle lights at night) but there is no highway noise. The numbering on the sites is odd because I can't find 60+ sites but that's how they are numbered. You do need to camp in the designated spots and the forestry service does come through and kick you out if you aren't. 

The bathroom is very simple. One men's and one women's. There is a sign that the bathroom is maintained by volunteers. I've always seen it stocked with toilet paper but the floor is normally dirty and the trash is half full. So far even in the cold weather the campground has been very busy so I imagine during the summer getting a spot could be tricky. From what I can tell most sites could be reached by a car and had room for smaller trailers or tents. The fire pits are just rock rings so be prepared to need to work on it a little
