On Thanksgiving Day of 2010—before her life as a nomad began—Linda May sat alone in the trailer where she was living in New River, Arizona. At sixty, the silver-haired grandmother lacked electricity and running water because she couldn’t afford the utility bill. She couldn’t find work. Her unemployment benefits had run out. Her older daughter’s family, with whom she had lived for many years while holding a series of low-wage jobs, had recently downsized to a smaller apartment. With three bedrooms for six people, there wasn’t enough space to move back in with them. She was trapped in a dark trailer with nowhere to go.
