Commercial for Luray Caverns, Virginia; begins with a fade in shot of the Luray Caverns; male voiceover: “it was an incredible discovery: an underground world like nothing on Earth! A world of excitement for years to discover this year, at Luray Caverns! (shots of stalagmites) Towering columns, fantastic formations, music on the only stalag-pipe organ in the world! Golf, tennis, antique cars-just 15 minutes from I-81 in Virginia’s Shenandoah Valley, with a gas station on the premises-” (ending cut off)
