Journey across the contiguous 48! Find a path that touches each state only once. BUT, make your journey as alphabetically early as possible.
Each state can be visited ONLY ONCE. Border crossings must be via land or road.
There are many one-touch paths through the states. At each junction, choose the ALPHABETICALLY EARLIEST adjacent state that will still allow a one-touch path to be completed.
e.g. from Oregon, the alphabetically earliest adjoining state is California, but this might render a one-touch path impossible by making Washington a dead end.
