Off the Map The Big Picture with Kal Penn : Season 1 Episode 12

You’d think after thousands of years of exploring and mapping the earth that we’d know where everything is by now. Well, we don’t. Not even close. We’re going on a global quest to reveal the mislabeled, the mysterious and the just plain missing places off the map. We travel to Washington, D.C., to discover that the U.S. government has its own maps, and they reveal a very different country where top secret installations are connected by unmarked roads and underground tunnels.
