We're going bi-coastal on the show today with stories about education and eating. First from New York:  What would it take to change the lives of poor children?  Not one by one, but in big numbers, and in a big way.  That's the question that led Geoffrey Canada to create the Harlem Children's Zone, a place to test new and controversial ideas about poverty and education.  We'll speak with author and journalist Paul Tough  about his experience writing his book about the Harlem Children's Zone, and the future of this innovative experiment.  

Plus we'll have a special presentation from our friends at Next American City.  As part of their Urban Nexus series, they've brought in Mark Vallianatos of the to tell us about the transformation of Los Angeles from an agricultural hub to a sprawling metropolis, and how it might regain it's agrarian heritage.
