Charles Johnson was living in St. Louis, married with a young daughter, and he had no job. He looked around, and decided he'd try trucking. There was this company offering to train and hire drivers, so he signed up. The only problem was, he couldn't read. Jonathan Menjivar reports on how Charles traveled all across the country making deliveries, without ever consulting a map. And without ever telling anyone—even his own wife and brothers—that he couldn't read. The literacy program where Charles learned to read accepts volunteers. Their website: LiteracyChicago.org.
