Great info Charlie! I've been to Chattanooga many times, it's a great place to visit.
I was staying at the Chattanooga Choo Choo Hotel 2 years ago in one of the train cars. The Songbirds Guitar Museum is on that property and was under construction when I was there. It looked interesting but was off limits. I will definitely want to visit there again.
Chattanooga is a very historic town. Aside from the Choo Choo, there was a lot of Civil War stuff that happened there including a couple of changes between the North and South during the war. There are many Civil War Museums and Parks in the area and all are very interesting.
Great places to visit if you go:
The Chattanooga Choo Choo - Hotel and historic site. Songbirds has a page on this site.
Ruby Falls - Explore caves
BBQ Joints, there are at least a dozen - I love
Sticky Fingers.
Aretha Frankenstein's - Punk Rock Waffle House - Awesome Pop Culture (Old Cereal Box Covers all over). The Hard Rock Café for breakfast.
Take a weekend and spend at this great town.
