Having recently given up "mainstream media" (read: I no longer pay any mind to the news), I find I've developed a taste for podcasts. I've come a cross some real gems as well as some real duds.
One of my favorites, though is
Backstory with the American History Guys. I've enjoyed many of their offerings, but last October they produced a real treat:
American Spirit: A History of the Supernatural. If you have an hour to kill, and would like to learn some interesting things about America's love affair with the kooky and spooky, click the link above and listen to the show directly from their website. (It's also available free on iTunes.)
