People these days often forget just how close the world was to complete and utter annihilation during the Cold War. In those days, the average person was at a heightened state of alert pretty much constantly. And incessant paranoia can make people do some crazy things — things like building enormous bomb shelters into hillsides made from the frames of old school buses. That's exactly what Bruce Beach did. Beach (pictured below) began construction on the Ark Two shelter during the early 1980s in the small Canadian village of Horning's Mills, which is just north of Toronto.

Looks pretty cool, right? So how do you secure your place in the shelter ahead of the apocalypse?

Beach says that he would not charge money for a spot in the shelter. In exchange for "sweat equity" and active involvement in the Ark Two community's various activities, a person living near the shelter could secure their place in case of a disaster.
