I found this on freecampsites.net.
This is a real small strip of BLM land in the Tucson area. While it was convenient for me for a one night stay I would stay there any longer than one night as there is a lot better BLM just west of here.
The generator noise would have bothered me if I could have kept my windows open during the night, which is how I prefer it. It was too cold here at night to keep my windows open. I was there in a second week of October 2018.
I did have a great Cellular Connection on Verizon.
