ROCKLOBSTER,
A few years ago the wife and I drove up the coast of Maine and stayed at Samoset for a few days about three days before it closed for the season,
Visited little lobstering towns put away for the winter and found Maine to be most beautiful along the coast.
Harsh and rugged but quitebeautiful.
It truly is. Unfortunately, Summer comes every 51 weeks.

We like Boothbay Harbor, though there are plenty of other spots along the Maine coast during the off-season.
What catches you is the quiet, once the tourists are gone, combined with the scenery. Face east and you have the rocky coast with scenic little harbors and "pocket" beaches. Turn west and there is the New England forest, which explodes with color in early October. And all of it is so thought-drivingly quiet.
(Potential guests might be amused to know there are leaf-peeping cruises up the rivers during the fall, then return to a tiny bed & breakfast for the night ... oh yeah!)
We native yankees (small Y), love our part of the country best during the autumn.
