Ah yes, the famous "Stage Curtain" at the cave...remember the Ethel Merman version of America the Beautiful while a slide or short film of a waving American Flag was flashed upon the rock wall? Classic roadside Americana, circa the 1960s and 70s! And that lovely picture of the "brand new" Grand ole Opry House in Nashville at the Opryland theme park! It was country, when country wasn't cool! Thanks Rube, post some more shots of that collection, please!
