I'm going to ride the Natchez Trace to see Mammoth Cave in Kentucky. I'm starting in Bryan, Tx. and probably going through Alexandria, La. on my way to the start in Natchez, Mo. and then ride the Trace to Kentucky. Any "must see" places or thing along the way? Recommended route back to visit interesting roads, places or sights. I have 11 days total due to a concert that I have to attend on May, 20 and my 47th anniversary that I must attend on June, 1. It's about 1,000 miles one way without side trips. There will be side trips.
