Speaking of the Pentagon. The legend of the Pentagon hot dog stand

Theres a five-acre park in the middle of the Department of Defenses Pentagon headquarters, and a small one-story structure sits in the bullseye center of the lawn. Some say that during the Cold War, Soviet satellite reconnaissance closely watched the mysterious spot, which attracted large groups of military brass at precisely the same time every day.
Good story. I enjoyed that with a smile
