Lots of people from Appalachia came to cities like Indy, Cincinnati, Dayton etc. for work in the 20th century. This convergence is well reflected in Indy's architecture. For example, the house in frame #41 would look right at home in Atlanta or Charlotte.

Maybe I-70 (another artificial boundary) more accurately reflects where the dividing line between north and south ought to be, but that too is a generalization. There's much debate, for example, about the Southern qualities of modern-day Maryland, and southward migration from the Midwest and Northeast has blurred the line somewhat to the south. 75-100 years ago it was Southerners moving to Northern industrial cities like Detroit.

There's always been migration every which way in US history, making classifications such as what place belongs to which region difficult.

Thanks for the insight!
