alfresco , The Baldwin sisters did own a car. Remember in The Homecoming, John Boy and Hawthorne went to their house to borrow some gas. When one of the sisters asked the other where they keep the gas, the other replied, “In the car, you ninny,” or something like that.
Edited: I did a little research. The Baldwin sisters’ car was a 1925 Studebaker.
In one episode, John-Boy mentioned going to Richmond, and one of the sisters said "Oh, we haven't been to Richmond in 30 years" - and yet it's only 3 hours away - well, maybe a little longer, back then. And I can't remember if they ever owned or drove a car? I'm not sure. (Please, correct me if I'm wrong). I know, in one episode they seemed helpless controlling a car that kept endlessly going in circles in front of the Godsey's store.
Their car appeared quite regularly throughout the series. Miss Mamie usually did the driving and, on the rare occasions when Miss Emily got behind the wheel, she usually proved quite adequately that she didn't know how to drive. (More to the point, she didn't know how to stop.)
As for Richmond, there really wasn't a need for them to go. What they couldn't get at Ike's, they could get in Charlottesville, which was much closer than Richmond.
Another reason I loathe Olivia is her forcing the children to memorize Bible verses as a punishment (or penance if you want to call it that). This is a sure fire way to ingrain in children a hatred of reading the Bible and for them to associate it with punishments and other negative things. Completely opposite the attitude a parent should wish to provoke.
