The Bigfoot Show is the best bigfoot podcast you're not listening to.
That's saying a lot, because there are a LOT of bigfoot-themed podcasts out there. Some are good, and some are painful to listen to, but The Bigfoot Show is great. The hosts bring just the right blend of skepticism, science and humor to the oft-ridiculed subject. And yet several of them have had encounters that they can't explain even from a skeptical point of view, which makes for a fascinating discussion. (I know from personal experience; I've been a guest on the show.)
Could there really be an undescribed, upright, bipedal ape wandering the forests of North America? If you're even remotely interested in the subject, you need to check out this show.
