Host Christopher Plant sits down with Inga Saffron to talk about the transformation of a city left behind. They start with Inga’s perspective on moving back to Philadelphia in ’98 and trace the architectural developments of Philadelphia through to the construction of the Comcast towers.   Inga Saffron is a Pulitzer Prize winner for her criticism of architecture, a writer for the Philadelphia Inquirer and author of Becoming Philadelphia: How an Old American City Made Itself New Again, published this year by Rutgers University Press.
