Walmart has a policy of welcoming weary travelers to stay the night in their vehicles in its supermarket parking lots. An unintended consequence of this policy is that people without homes have taken up permanent residence in their vehicles alongside the people who are just passing through. For three weeks last summer I too slept in a car outside two Walmart stores in Flagstaff, Arizona, documenting the inhabitants of this ever-evolving community. This is life in the modern world. We eat, we sleep, we reminisce, and we use the bathroom beneath neon signs.
