There aren't many good options. Route 27 south from Stratton to Kingfield, Route 16 east over to Solon, Bingham, and Abbot, then Route 6 north to Greenville or Rockwood. Mobile phone coverage will be limited. Good luck,
Jerry Stelmok has a nice show with some canoes at the Monson Arts Gallery if you want to take a break on route. The link has more details. The opening last week was fun as shown below.
