flyover country

The middle class Midwest that is typically "flown over" by scheduled airlines in their hops between their major hubs. The bounds of flyover country vary from urbanite to urbanite. People from Chicago tend to think it runs from the Mississippi River to the Rockies (and also Indiana). Bay Area, it's the San Joaquin Valley east to Chicago. New York, it's anything that is not within an hour's drive of The City.
