TriPod: New Orleans at 300 returns with a new TriPod Xtra segment. As part of the New Orleans Museum of Art’s literary ‘Arts and Letters’ series, Laine Kaplan-Levenson spoke with sociologist Peter Marina in front of a live audience about his book ‘Down and Out in New Orleans.’ The two discussed the various informal economies in New Orleans, and alternative lifestyles people choose as a way to live outside of mainstream society. Laine starts the conversation with what Marina’s book is inspired by.
