The songs were intended to be sung at rallies, meetings, marches, and demonstrations in order to "make us feel stronger, part of the bigger movement of people everywhere working to close the weapons plants and end the nuclear threat.”   Built in 1952, the Rocky Flats nuclear weapons facility was located 16 miles northwest of downtown Denver and covered an area of 11 square miles, including the site and buffer zone. For nearly 40 years, parts for nuclear weapons were produced at the plant, utilizing radioactive materials and more than 8,000 chemicals. Rocky Flats ceased weapons production in 1989, and cleanup of the site lasted from 1992 until 2005. In 2007, the United States Department of Energy transferred 4,000 acres of land on the Rocky Flats site to the U.S. Fish and Wildlife Service to establish the Rocky Flats National Wildlife Refuge.   There is lots of information available on the history of Rocky Flats in the Western History and Genealogy Department.
