As I understand it, the Tennessee property began as Goldrush Junction. When the Herschends obtained the property, they changed it to SDC Tennessee, and when Parton came on board, they re-visioned it to her brand of Dollywood, where it has, apparently, thrived.
The property in Branson has always been named Silver Dollar City - unless we are sticklers for the times when it was Marvel Cave Park in those initial years before they handed out silver dollars for change.
Anyone want to correct that or add to it? There has to be more discussion about it in these forums somewhere.
