Peter Fletcher, a Michigan alumnus and chairman of the State Highway Commission with a "sly sense of humor",[1] ordered the inclusion of 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).

[3] In their 2012 obituary of Fletcher, AnnArbor.com noted that the maps containing the fictional cities had a limited print run and have become collectors items.

[1] The map's publication has also been noted as a good luck charm for the University of Michigan Wolverines that year; the team beat their arch rivals 14–3 in the 1978 edition of The Game,[2] which was once called the greatest North American sports rivalry by a writer for ESPN.com.

Joe comic book character Road Pig is recorded as having been born in Goblu, Michigan.

In their description, it refers to fake towns on a map created by cartographers to deter copyright infringement.
