OK, I will have to be diligent about digging out my Chattanooga material.
For the Chickamauga and Missionary Ridge tours, I used Steven Woodworth's "Chickamauga: A Battlefield Guide." It includes not only a day-long tour of the Chickamauga battlefield, 20 stops with at least one map for each stop, but a Lookout Mountain/Missionary Ridge tour.
The walking tour of downtown Chattanooga was my own creation and that'll come by Email to those interested.
