I am going on a roadtrip with the family (ages 17 - 35) to visit my father in law for thanksgiving. we are leaving miami on a sunday. None of us have ever driven on an 18 hour drive. We would like to take opportunity and make some sightseeing stops along the way. We plan on taking I-75 all the way.. Can someone recommend any fun stops from Georgia to Tennessee? 

(we do not wish to tour coca-cola or cnn in atlanta) any other recs?? 

Thank you,
