This part here really miss's the good stuff.
The Ozark's in Mo. and Ar. are good ,but your line is a transit N to S. through them. Birmingham to Atlanta, what are you going to see? Barber's outside of Birmingham is worth it , but why go to Atlanta ?
Anyway the good riding is North Ga.,Eastern Tn. ,Western N.C. Western Va., West Virginia and Eastern and Central Ky. Millions of cruves,hills and valleys.
It's your trip ,enjoy the good parts.
If you pass through Ky. and need some work or a place to stay, message me I have both. I raise tobacco and cattle and the fun never ends.Good riding too.
