What is an example of a vernacular region?

Vernacular regions are geographic areas in which people share specific cultural or linguistic traits that distinguish them from neighboring areas. One example of a vernacular region is the "Blue Ridge Region" in the United States. This region includes parts of several states in the Appalachian Mountains, such as Virginia, North Carolina, South Carolina, and Georgia. People in the Blue Ridge Region share a distinct culture and dialect, which is reflected in their music, food, and speech patterns.
