Imagine what you can learn about a city by picking up the garbage of the people who live there. Simon Paré-Poupart, a sociologist and garbageman in Montreal, joins host Krys Boyd to discuss his life on the back of a garbage truck, why he prefers the term G-men to garbagemen, and the people who are called to do this dirty job well and with pride. His book is “Trash!: A Garbageman’s Story,” and his companion piece in Harper’s is “The Conscience of the City.”
