Natchez Trace PKWY - doable?

We have been on it several times. We love to stop for a break at Metal Ford and Emerald Mound. Rocky Springs, near the southern end of the Trace offers a chance to see and feel the history of the Trace also dry camping in a lovely setting, if the boy scouts are not there. You might want to pick up Nevada Barr's "Deep South" and "Hunting Season" before you go. She writes murder mysteries using National Parks for her background and Anna Pigeon, Ranger for her detective. Excellent reads and you can follow the stories on the ground as she is very careful to represent the parks accurately. It made our first visit to Rocky Springs very meaningful and fun.
