Boyhood home of Mark Twain. Hannibal, Missouri. Toured the museum while there. Later watched a three and a half hour autobiography during an eight hour layover in the airport.
I remember factories in Steelville, Illinois. At lunch the whole town was busy with people in white clothes. They made pasta there among other things.
Holly Springs, Mississippi. Long drives back and forth to the hotel & work-site but met two new friends and we walked four miles most everyday there on a track near the hotel.
Book Store in Cookeville, Tennessee. Can't remember much.
