In a world where rational, scientific explanations are more available than ever, belief in the unprovable and irrational is on the rise: from Atlantis to aliens, from Flat Earth to the Loch Ness monster, the list goes on. It seems the more our maps of the known world get filled in, the more we crave mysterious locations full of strange creatures. Dickey visits the wacky sites of America’s wildest fringe beliefs—from the famed Mount Shasta where an ancient race are said to roam, to the museum containing the last remaining “evidence” of the great Kentucky Meat Shower—investigating how these theories come about, why they take hold, and why as Americans we keep inventing and re-inventing them decade after decade.
