Episode No. 321 is a holiday weekend re-air of host Tyler Green's March conversation with National Gallery of Art curator Diane Waggoner.  

Waggoner is the curator of “East of the Mississippi: Nineteenth-Century American Landscape Photography.” The story of America’s 19thC photographic history has mostly run through the West. Waggoner’s exhibition instead examines photographers working between the Mississippi River and the Atlantic Ocean. It's at the New Orleans Museum of Art through Jan. 7.
