Almost every major city is defined by a set of zoning regulations - a map that says exactly which types of buildings can be built in which areas, and what you're allowed to use those buildings for.  M Nolan Gray, a city planner and author of the new book 'Arbitrary Lines', joins the show to discuss zoning.  How did our modern system of zoning develop in the 20th century?  What impact does zoning have on our cities? Is zoning to blame for the housing affordability crisis?  And should we reform or abolish the systems of zoning that are holding us back?
