I've been listening to Econtalk for five or so years. My favorite guest was Chuck Marohn of Strong Towns on urban development and the future of American cities. He makes the case against car-dependency and sprawl from the point of view of municipal finances. After hearing that talk, I started listening to Marohn's podcast, and I find it similarly excellent, though it's sometimes a little less polished. He talks about ways towns have fixed their neighborhood, general principles about traffic and congestion, and occasionally ridicules particularly bad projects, among many other things. Marohn is pretty aggressively apolitical; he's been invited to talk by groups as varied as environmental groups and tea party gatherings (back in those days). His perspective is also probably different from most people in that field. He lives in a small town, having just moved after living way outside the town for 15 years. He's a civil engineer-turned urban planner-turned-non profit president, and the organization is impressively well-run.
