The drawback to my Chattanooga plan was that Nashville would be shortchanged. Still, I looked up places of interest and picked out the Parthenon as a likely quick photo-op. Why had I never heard of it before? It is a full size replica of the Parthenon in Greece built in the 1920s. It's very impressive in person, photographs don't do it justice. Perhaps you should see for yourself.
