Pennsylvania Legacies

Chuck Flink wrote the book on greenways -- literally. 1993's "Greenways: A Guide To Planning Design And Development," co-authored with Robert Searns and addressed to the planning community, helped launch a global movement in landscape architecture. Now he's making the case for greenways to a broader audience in his new book, "The Greenway Imperative: Connecting Communities & Landscapes for a Sustainable Future."
