Heading for Nashville/Murfreesboro and beyond to Chattanoogo/Lookout Mt/Chickamauga/Missionary Ridge next month. Hope to have some more pictures from those areas.
Nashville/Murfreesboro don't have much in the way of actual battlefield left, but you can see a decent museum. Likewise, it should not take you long in Chattanooga, there are only a few isolated markers preserving sites there, mostly along Missionary Ridge. Lookout Mtn is a must see but won't take long unless you decide to "See Rock City". You'll know what I mean by the time you get there.

We used to live in Rome GA about 35 miles south of Chickamauga. It's a great battlefield with lots of preserved sites, but it will require a lot of walking through woods and has no real great vistas like Gettysburg.
Chickamauga lends itself well to isolated hiking trails giving you a reason the fighting was so confused there at times. Pack a picnic lunch as once you get in the park there is nothing for miles around. You can easily spend 2 days here; if you stay in Chattanooga you can do that stuff in between visits to the Chickamauga field.
Enjoy your trip! I'm putting together some more Gettysburg pictures now.
What's cool is after your trip I am quite sure you will divide that Chickamauga /Chattanooga region up in AACW in just the right way!
