Such was the assessment of Bob Vinson, the graveyard shift supervisor at Harvey's Wagon Wheel Casino in Lake Tahoe, Nevada. The "it" was a curious piece of equipment of unknown origin loitering conspicuously in the cramped side room. All of these switches were situated in the down position except for #23, which was toggled up—an oddly ominous asymmetry. An envelope with "Harvey's Management" typewritten on one side lay on the carpet alongside the object. Vinson soon returned with companions, having summoned members of Harvey's Wagon Wheel Casino security, who had subsequently summoned sheriff 's deputies and the fire department.
