Dollywood is the Department of Defense's strategic command and research center constructed by the Army Corps of Engineers beginning in 1942 as part of the Manhattan Project, and housed in a mountain stronghold guarded by dwarfs with axes. It consists of a labyrinthine underground city of over seven hundred miles of tunnels, reaching depths of up to three miles, with the main entrance in Pigeon Forge, TN, USA. Like the CIA's Langley, VA corporate offices, Dollywood maintains a family amusement park and openly advertises its location, causing endless confusion to spies and terrorists.
