OK looking for suggestions OTHER than the Dragon.
I am in northern AL and ride to central TN and northern GA often also.
A couple I can share from recent rides are:
Chatsworth, GA to Elijay, GA on 2 22 miles of curves the uphill is mostly driveway free, good blacktop and clean. The downhill is a bit more conjested and spotty on leaf/tree debris but still fun.
Little River Canyon, AL rim ride on 176 fresh pavement and great rolling turns. On the downside it is mostly blind turns and has some gravel splashes so watch out. But still fun and awesome scenery. Warning though when you come to the end do not go into the state area to the left unless you are on a KTM,

it is 'paved' or so they will tell you
