Charles Johnson was living in St. Louis, married with a young daughter, and he needed a job. He looked around, and decided he'd try trucking. This company was offering to train and hire drivers, so he signed up. They trained him and put him on the road. 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. Originally aired on This American Life.
