Hi, Anyone have any route recommendations for Columbus to Asheville? This will be our second outing/ longest distance with our PUP, and we have to drive in the middle of the night. Google gave 3 options listed in order of travel time: (1) US33/I77/I81 - 445 mi, 7h9min (2) US23 - 404 miles, 7h22min (3) I71/I75 - 486 mi, 7h41min I was inclined to stick with interstates, but heard the first route was through the mountains and very curvy. US 23 is through many towns, so if we had any issues, assistance wouldn't be far away. ANY info appreciated. We will be departing Aug. 29. Thanks!
