If you don't know it, I highly recommend The Big Dig podcast. Very Massachusetts history focused: they dig into some place where government / policy intersect with the real world, and document and explain how that policy actually was implemented and affected the populace. Every season is very different (a highway mega project, the state lottery, a fishing scallywag) but each is told in delightful depth. I really recommend it if you're the sort of person who is in to policy or recent history.
The Big Dig
Seemingly dry topics become gripping political dramas in this Peabody Award winning show from creator Ian Coss and GBH News. Each season of “The Big Dig” uncovers a different facet of society in Boston – infrastructure, gambling, food, healthcare – together the pieces connect to tell the story of modern America.
