The road making the loop is one way, but be careful as some folks ignore the one way. Accidents can happen. Once you get past the pavillion, the road is one-way down hill.
The top map is the newer one. You can see the locations of the campsites easier. The ones up by the pavillion, where the restrooms are located, some have electricity. There are several community water spigots along this road. Note that not all of them work at the same time.
I now have some photos of the event area and the area just to the right of the CCC museum which should better detail these areas.
