Quote:Deep in the West Virginia woods, in a small cabin powered by the sun and the wind, a bespectacled, white-haired man is giving a video tour of his basement, describing techniques for the long-term preservation of food in case of “an emergency.”

Quote:What is atypical is that the owner of this cabin is Roscoe Bartlett, the longtime Republican congressman from Maryland. Over the past two decades, he has developed a following as one of the country’s premier proponents of preparedness against impending doom, even urging the more than 80 percent of Americans who live in urban areas to relocate.

Quote:“There are a number of events that could create a situation in the cities where civil unrest would be a very high probability,” Bartlett predicts in “Urban Danger,” a documentary that features the cabin tour. “And I think that those who can and those who understand need to take advantage of the opportunity when these winds of strife are not blowing, to move their families.”
