The Siegfrieds' lighthouse on Chesapeake Bay.
Location of a lighthouse where Siegfried and his daughter Gretchen have hidden a missile with a nuclear warhead.
[GS95 Episode #6: "Wurst Enemies".]
Reality Check: Siegfried gives the address as "Sands Point Harbor". However, the Sands Point Lighthouse is in fact located in Nassau County, New York, on Long Island. More likely, the Siegfrieds' headquarters is at Sandy Point, north of the Chesapeake Bay Bridge, Maryland.
