A couple suggestions for you:
Just north of Atlanta GA you should visit Stone Mountain. From Wikipedia: Stone Mountain is well-known not only for its geology
, but also for the enormous bas-relief
on its north face, the largest bas-relief in the world.
The carving depicts three figures of the Confederate States of America
: Stonewall Jackson
, Robert E. Lee
, and Jefferson Davis
From there hit 1-20 heading west into Alabama and visit Barbers motorsports park just east of Birmingham, AL. There is one of the best motorcycle museums period!
Enjoy the ride!
