Infrastructure safety is high; the interstates are well-lit and monitored by state patrol. However, rural sections may have wildlife crossings (deer) at dawn/dusk. Keep an eye out for livestock on smaller state highways.

Fatigue management is crucial on this long drive. Break up the drive with a stop in Columbia, MO, a college town with a vibrant downtown. Alternatively, overnight in St. Louis to explore the Gateway Arch before heading south. Hidden off-route spots include the small town of Rocheport, MO, with its winery and trail access.
