Today, I began heading north. I was originally scheduled to head up into the Carolinas tomorrow, with a stop to visit friends in the Raleigh area, a moderate drive of 8.5 hours and 451 miles. But this leg now begins with a detour through Chattanooga to visit and photograph the renowned Tennessee Aquarium and the Walnut Street Pedestrian Bridge. So, this stage began with a short trip of 3.5 hours to Chattanooga.
