Yeah, it would be a long drive down to northern Georgia and I also think we would have to take off the Friday and Monday. There's a possibility of stopping by the Air Force museum in Dayton, OH (if you like that kind of stuff) depending on which route we take (I've been there before).
I not keen on driving into a hurricane either.
I think the climbing numbers you have are half of the actual numbers. Highlander should be 11,000, Six Gap they say is 13,000. I'm not sure about the others, but I don't trust MapMyRide cumulative elevation numbers.
I check the hotels in Dahlonega and they are already fully booked. They had some rooms left in Gainesville, 20 miles away.
