Great site just off 40
Found this site using this app - just off 40 (opposite side of road than in the Dyrt map) and super easy to find at 10pm at night. Rolled into a site in my sprinter, put up the shades, and went to sleep. Left before the sun came up so I really have no idea what it looks like - but the pit toilets work, lots of people there - was lucky to find an open spot.
