...here would be one vacation I'd take, centered in the Deep South. (Was just inspired by learning that a home that F. Scott and Zelda Fitzgerald once briefly lived in [1931-32] in Zelda's home-town of Montgomery, Alabama, is both a museum AND part of the AirBnB circuit, for only $135 a night!)

My potential (though not likely) itinerary:
Fly in to Atlanta. Margaret Mitchell/GWTW site tours. (One day; spend night; rent car.)
Drive out to visit Ginny's grave in McDonough, Georgia, and briefly to the area where I lived for under a year as a 3rd-grader (Warner Robins AFB). Drive on to Montgomery.
Montgomery, Alabama: Visit Fitzgerald house/museum and locations where Scott/Zelda met in 1918, and where her parents once lived/where she grew up (now torn down). Spend night in Fitz AirBnB (2nd story of the house above the museum).
Tremont and Tupelo, Mississippi: Drive to visit birthplaces/museums of Tammy Wynette and Elvis Presley, respectively. (One day; spend night in cheap local place)
Memphis, Tennessee (Elvis's Graceland mansion), and Shiloh Battlefield. (One day; spend night in [probably very expensive] hotel)
Nashville, Tennessee. Ryman Auditorium and other historical country-music club sites downtown, plus George Jones's gravesite. (One day; spend night) Turn in car, fly home to Austin.
I think this would be a GREAT 7-to-10-day vacation! (Trouble is, I don't know anyone else who does! My tastes are very specific! For one thing, when my mother, younger brother, and myself moved from Texas to Georgia pre-3rd grade to join my military father, my mother drove us all that way through the Deep South. Beautiful and mysterious country (unlike the more hard-scrabble-looking Texas, except for its Eastern woods). I would like to see both the East Texas pines and these southern states again.
The big-city Atlanta and Nashville parts of the trip would probably NOT be the highlights for me. Aside from the scenery while driving, I'd be looking most forward to the Fitzgerald house and the museums and the graves.
