I was staying at the Inn at Vaucluse Spring over the weekend and was driving around the countryside and drove past Carter Hall. Yup, it is a real place just outside of Millwood Va. I am going to contact them to get a tour up if anyone wants to do a Saturday. The place is now a conference center but, they do tours of the house and grounds. Let me know if you are interested. Maybe a day of the house and some vineyards.
Here is a WIKI about the place.
