oops, forgot to tell about the trip into Chattanooga...through a part of the river that follks refer to as the Grand Canyon of Tennessee...talk about cliffs and mountains...windy river passage...we saw both sides of several mountains...what would take you an hour by car took us over four hours...but the scenery was delightful and since we were going this right direction we had a pretty nice breeze....by the time we arrived in Chattanooga, it was hot hot hot...glad to be pluged in and AC blasting.
