This came up in another thread and I figured we could spin off our own on this. I used to listen quite a bit when I was commuting but that has since tailed off. Some of my favorites: Crimetown - Only one season out now but tells the story over many episodes about some of the criminal history of Providence, RI. Subsequent seasons will branch into other cities. Stuff You Should Know - Each show is about a random topic. Some examples are How Landfills Work, How Lighthouses Work, How the Pony Express Worked, etc Civil War Talk Radio - Awesome and detailed episodes about various aspects of the American Civil War. Some very deep and off the wall topics here. Money for the Rest of Us - About investing, general topics about the dollar, finance, etc What are you listening to?
