The highway system of the United States was designed for efficiency, not experience. Interstate routes between major cities are straight, fast, and brutally boring. The state routes and county roads that connect small towns contain the America that road trips are meant to reveal.
A successful road trip requires more planning than a flight-to-destination vacation, but the returns are proportionally greater. That unexpected side road leading to a covered bridge or local diner becomes part of the story rather than something seen from thirty thousand feet.
The Route Question
Popular routes like Route 66 are popular for good reasons, but their popularity means traffic and commercialization. The parallel routes one state over often provide the same geographic diversity with a fraction of the crowds.
The Practical Elements
Download offline maps for areas with unreliable connectivity. AAA membership provides valuable roadside assistance and discounts. Bring more snacks and water than seems reasonable; rural stretches between services can stretch for hours.
