States
Use state pages when you want the broadest practical planning layer before choosing a route section, town, or trip. These are the current Route 20 state gateways on the site, including the full Iowa-to-Oregon western chain and the strongest current eastern and mid-route states. For a broad western start, begin with Iowa. For a broad eastern start, begin with New York or Massachusetts depending on whether you want the Finger Lakes side or the Boston finish.

Looking for narrower regional pages too?
Use the full regions index when you want the state gateways and the smaller subregional pages on one page. After a state page, the usual next move is one route section from segments, then one stop or anchor town from places, then a bounded weekend or drive from trips.
