We are driving from texas through arkansas on into east tenesee. on the way back we will drive through mississippi and louisiana (spelling?). this will take place mid june and will be sticking to the interstate highways except in mississippi we will take the natchez trace road. if you know of any interesting sites in those states, let me know. the places don't have to be train related. our boys are ages 5 and 2. thanks everyone.
