Following the success of “Nomadland” at the Academy Awards, there is a growing spotlight on the real nomads featured in the movie and their lives off the grid. Sue Anne Carlson, who played herself in the movie, has been living in a tiny Prius for 12 years. Bob Wells is also featured in “Nomadland,” playing himself. He’s been a van dweller for 19 years after going through a divorce and quitting his job at a grocery store. On the night of the Oscars, Wells couldn’t believe what he saw.
