The lost colony of Roanoke was a group of settlers who tried to make it in this country back in the 1500s, but they mysteriously vanished. Over 100 people gone and all they left was a lousy skeleton and a one and half tree carvings that read "Croatoan" and "Cro". Was it aliens? Did they eat each other? Did something else eat them? Was it something far more bizarre? Alison, Jeff, and Rob try to get the bottom of what happened there. It wasn't as hard as you'd expect.
