Renowned Author Howard Mansfield returns to Infrastructure Junkies to discuss two more chapters of his book, The Habit of Turning the World Upside Down.  In this Season 4 finale, Howard tackles "The Last Medieval Claim" by recounting some of the earliest battles for American soil which occurred in the courts across the ocean, and involved people who never set foot in North America. Then the conversation turns to "The Pipeline in the Neighborhood" where the human effects of a massive infrastructure project are once again examined.   This episode of Infrastructure Junkies is generously made possible by Blackbird Right of Way, LLC, experts in the Uniform Relocation Act benefitting projects all over the United States.
