Heading to Dollywood tomorrow in Pigeon Forge. I assumed I will take the I-40 route past Ashville and into TN. But the google map genius shows a 421 to I-81 route is only 10 minutes longer. I am coming from Efland NC (Burlington) heading west. Either of those particularly better or worse or some other ideas to get there? Just a car or truck (haven't decided yet) no trailers or anything. Just want the easiest drive. Leaving around 9AM Monday so any quick suggestions would be appreciated.
