Scattered throughout New Mexico, in cities like Santa Fe and Albuquerque, as well as in small towns like Cordova, Las Trampas and El Rito, are dozens of historic mission churches. These adobe and stone structures date back to the 19th, 18th and 17th centuries, and many are in danger of collapse. A new non-profit, Nuevo Mexico Profundo, is helping to maintain and restore them. One of the founders, writer and historian Frank Graziano, joins us to talk about the organization's mission.
