Walking across US state borders: A to Z

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.
