Fourth Coast
The Fourth Coast is a reference to the Great Lakes region, with a particular reference to Michigan, since it has "four" coastlines, and is the only state that does. A few local businesses in Kalamazoo have adopted the name (such as the "Fourth Coast Cafe"). It seems that the term is gaining in popularity and is mentioned often in blogs when referring to Michigan.
