Beatosu and Goblu are two non-existent Ohio towns that appeared on Michigan's official highway map as a reference to the University of Michigan and their rivals, Ohio State University.

Beatosu and Goblu are two non-existent Ohio towns that were inserted into the 1978–1979 official state of Michigan map. The names refer to the slogan of University of Michigan fans ("Go Blue!") and a reference to their archrivals from the Ohio State University (OSU).
Peter Fletcher, a Michigan alumnus and chairman of the State Highway Commission, inserted the fake towns of "Goblu" (near the real town of Bono, Ohio off State Route 2) and "Beatosu" (near Archbold, Ohio, just south of Interstate 80/Interstate 90/Ohio Turnpike at exit 25). In a 2008 interview, Fletcher explained that a fellow Michigan alumnus had been teasing him about the Mackinac Bridge colors: green and white, the colors of Michigan State University. Fletcher noted that the bridge colors were in compliance with federal highway regulations, so he had no choice in that matter; he did, however, have more control over the state highway map. Fletcher said that he thus ordered a cartographer to insert the two fictitious towns.
