We were a little confused here, as we thought the camping spots were the concrete pads leading up to the old airfield. But there are big rocks blocking the way from Rd 3536 to the airfield, so I don’t know if that’s a recent addition or what. There’s a large concrete pad on the west side of the rocks, and when we got there there was a nice looking (not sketchy) travel trailer set up for long term camping. Lots of trucks parked everywhere with trailers; they had hauled their ATVs in and were out riding for the day. They came back on their ATVs in the late afternoon, hung out for a few hours, then left (except for the trailer). All surprisingly quiet and respectful. 

Zero cell service with Verizon but ATT had good service, mostly. It would randomly drop now and then but it would come back. We found a good spot to tuck into for the night, while staying out of the way of all the trucks parked everywhere. Very quiet and serene.

This is dispersed camping so of course no amenities whatsoever. Please handle your waste appropriately and let's keep this area clean.
