As BackStory nears the end of its production, we’ve asked our listeners to call in with moments from the show’s history and compile their very own “Best of BackStory.”

We got some great responses covering a range of topics, each of them meaningful to the present moment in their own way.

So in this best of BackStory, we present three of our listener’s favorite interviews from the show. You’ll learn about the early U.S. Postal Service, and hear from residents of Hamlet, North Carolina as we explore the painful memory of a 1991 tragedy. Then, you’ll discover the long evolution of the Confederate flag’s design.
