This Week on the Radio: "Middle of the Night" Stories of people who are up while the rest of us are sleeping—some for work, some for play, and some for a free sandwich. Including the story of a woman walking alone at night, who encounters another woman walking alone at night, for the exact same reason, and a whole population of people haggling over the cost of oranges at 3 in the morning. Broadcast November 27 - November 29.
