US 23 also gains attention during college football season as it holds a direct connection between Ann Arbor, Michigan (home of the University of Michigan) and Columbus, Ohio (site of The Ohio State University) and the Michigan–Ohio State football rivalry. Each year at the end of November a convoy of fans travels either north or south depending on where that year's game is being held. Unsubstantiated rumors that the host state of that year's game has their state police (either the Michigan State Police or Ohio State Highway Patrol) force an increase enforcement of traffic laws along the route in their respective states to cite opposing fans adds to the rivalry.
