If you're looking for podcasts about strange stuff happening in small towns (and you've already listened to S-Town and taken an audio tour of Woodstock, Alabama) then you can't do better than these two:
1) Hysterical . . . this one investigates a spate of oddball symptoms-- tics, verbal outbursts, twitching, spasms-- that spread virally through the girls in an upstate New York high school in the town of LeRoy-- and the question is: was this mass hysteria, otherwise known as conversion disorder? or was it due to toxic chemicals or something environmental? a great one if you love The Crucible and the Salem Witch trials;
2) Cement City . . . two journalists stumble into a dying Pennsylvania town-- Donara, home to the Donara Smog Museum, which memorializes the Donora Smog of 1948, an air inversion containing fluorine that killed twenty people-- and they buy a house? a house made completely of concrete? and they get caught up in town politics and what it's like to live in a place with no bank, no grocery store, and no school, but a whole lot of camaraderie;
and while I recognize that these podcasts are presenting a very thin sliver of what it's like to live in a place that does NOT feel like it's the center of the world, and these podcasters have cherry-picked extremely interesting narratives of truly oddball events and these small towns just happen to be the setting, it's still really interesting to inhabit places like these, places that I will probably never truly understand, because I live in a fast-paced, densely populated, and expensive region of the country, with all the amenities and conveniences and ethnic restaurants and parks and high-end grocery stores and sky-high real-estate prices and even if I were to move to an out of the way rural kind of place, I'd never be able to pass as a local . . . you can take the guy out of Jersey, but you can't take the Jersey out of the guy.
