There are thousands of Wal-Marts across the U.S. that allow overnight parking for cars RVs. In some cases this had led to the development of whole communities.
Brooklyn writer and photographer Nolan Conway got to know some of these people while living out of his car for 3 weeks in Wal-Mart parking lots across Arizona.
"Within a week of being surrounded by these people I became lonely and unhappy. It’s one thing to stay in the Walmart parking lot, but it’s an entirely different experience living there. You can also feel quite vulnerable sleeping in your vehicle," Nolan wrote via email. 
Nolan plans on showing his series, "Waking Up At Walmart," in galleries soon. We've got the highlights here.
