The original Dixie Cragger(single Vol) was published a few years AFTER the road to Yonah was closed, and informs it's readers accordingly.
The book you may be referring to that Rob and Chris co-authored is a book titled The Deep South Climbers Companion.
Regardless, the OP already found Yonah and made his way to the cliff, as his TR indicates. My offer was simply so he'd have a guidebook with all the varoius Yonah routes described because he commented that he was having difficulty finding a guidebook with Georgia info in it. You know, trying to extend some "southern hospitality" and all that. No worries, plenty of Georgia climbing info available for free on mountain project.
