One historical oddity: near mile marker 40 on I-94, you cross the Michigan-Indiana border at a point where the state line makes a curious zigzag due to an 1817 survey error.

Kalamazoo is known for craft breweries and celery farming history. Michigan City's outlet mall and lakefront shops draw visitors year-round.

Road quality is generally good, but construction zones on I-94 near Battle Creek can cause sudden lane shifts. Winter driving demands caution on I-94's exposed sections where lake-effect snow accumulates quickly. Summer sees heavy tourist traffic near Michigan City on weekends. Rest areas exist at mile markers 24 (north of Flint) and 78 (near Jackson) on US-23, and at mile marker 44 (east of Kalamazoo) on I-94. Family-friendly stops include the Meyer's Lake rest area (playground, picnic tables) and the Michigan Welcome Center near New Buffalo. For pets, most rest areas have designated pet-walking zones.
