Well, I'm back, and will probably have to take tomorrow off to recover from the vacation. We went to Chattanooga and saw Rock City and the Aquarium. The rest of the family also saw Ruby Falls, but I didn't attempt that one since I knew I could never keep up.
We used a wheelchair at the aquarium, and I just loved it. Rock City was fascinating and beautiful also, though I had to "cane" it through. We just piddled along at my very slow pace, getting over when other groups started to back up behind us. I can't believe I made it through, but I did.
Had a great time, but don't want to go so far again. That long of a ride really tired me out just by itself.
