A retreat is a place of refuge for those in the survivalist subculture or movement. A retreat is also sometimes called a bug-out location (BOL). Survivalist retreats are intended to be self-sufficient and easily defended, and are generally located in sparsely populated rural areas.
While fallout shelters have been advocated since the 1950s, dedicated self-sufficient survivalist retreats have been advocated only since the mid-1970s. The survival retreat concept has been touted by a number of influential survivalist writers including Ragnar Benson, Barton Biggs, Bruce D. Clayton, Jeff Cooper, Cresson Kearny, James Wesley Rawles, Howard Ruff, Kurt Saxon, Joel Skousen, Don Stephens, Mel Tappan, and Nancy Tappan.
With the increasing inflation of the 1960s, the impending US monetary devaluation, the continuing concern with possible nuclear exchanges between the US and the Soviet Union, and the increasing vulnerability of urban centers to supply shortages and other systems failures, a number of primarily conservative and libertarian thinkers began suggesting that individual preparations would be wise. Harry Browne began offering seminars in 1967 on how to survive a monetary collapse. He worked with Don Stephens, an architect, survival bookseller, and author, who provided input on how to build and equip a remote survival retreat. He provided a copy of his original Retreater's Bibliography (1967) for each seminar participant.
