Indianapolis boasts the Milktooth brunch spot. Gary has a revitalizing arts scene, with the Gary State Line Center for the Arts showcasing local African American artists.

The primary highways are well-maintained, but Ohio's I-77 north of Marietta features steep grades and curves. Indiana's I-65 is straight but can be congested near Indianapolis. Fuel prices typically drop in central Indiana compared to Ohio. Plan for three refueling stops: Zanesville, OH; Richmond, IN; and Lebanon, IN.

• Gas stations: Regular intervals, but rural stretches (e.g., between Cambridge and Zanesville) can be sparse.
• Tolls: None on this route save for possible local tolls near Gary.
