Robert’s road trip is a thrilling but perilous adventure. His visit to Mexico expands his horizons and gives him a brief respite from segregation. He’s lucky to have a friend in Houston, since Texas is segregated, like the rest of the South. Otherwise, he may have had nowhere to stay, like in rural west Texas, where he’s effectively on his own. As Wilkerson frequently points out, he travels roughly 2,000 miles—much further than many international migrants.
