That section of Virginia is rural, Blacksburg itself is half the size of the suburb of San Diego I live in, and Blacksburg is the biggest town for 30ish miles in any direction.
As a predominantly White, redneck area, this isn't hard to imagine at all. There were *2* Asian kids at my High School while I lived in that area, a handful of Blacks and Hispanics, and an overwhelming amount of white people.
