My "birth city" of Oak Ridge, Tennessee. I can drive it like the back of my hand even though I haven't lived there since I was four. Oak Ridge has the highest Ph.D per capita in the country. The federal government created the "secret city" in the 1940s. My grandfather became one of the blue collar workers who worked on refining the plutonium for the atom bomb. There is a wonderful atomic energy museum and it is set in a truly beautiful place.
If you know "Elvira" only as a #1 country hit for the Oak Ridge Boys in 1981, you might not know that it was previously recorded by its author, Dallas Frazier, as well as Rodney Crowell, even Kenny Rogers and the First Edition.
