The podcast this week is all about lost civilizations - a little history, some of the very strange (and sometimes even otherworldly!) situations surrounding their rise and disappearance, and of course some spirited discussion about what scenarios could have led them to their fates. When we don't have the benefit of historical documentation to follow along with, a lot of the most recognized scientists and anthropologists out there can only make educated guesses as to what happened to these civilizations. We do, however, have a lot of new information since the last time you may have heard of places like Gobekli Tepe and Rapa Nui (Easter Island), for example.

We were joined on the show by quite a few beers, including the inimitable Pabst's Blue Ribbon and some great citrus IPAs including the seasonal Citra Hero by Revolution Brewing. Yum!
