I live in Nashville and did not know this tour existed. My daughter, who lives out of town, found it on line. What a fascinating and important aspect of Nashville history! Our tour guide was very knowledgeable and engaging. I thought I knew a good deal of Nashville history, but he taught me a number of things I did not know, which was wonderful. The morning tour may well be the better option, as downtown Nashville can get very busy in the afternoon. But even if you end up navigating the traffic and crowds, the tour is definitely worth it.
