Thanks Micca!
Being an historian, I'm drawn to historical sites. The lighthouse at Portland Head. It's called the most photogenic lighthouse in America.

Also, Cobscook Bay in eastern Maine, the tidal bore in the Bay of Funday. When the tide comes in, there is a wall of water tearing up the bay.

In Machias (My home town) the Burnham Tavern, where a gang of renegades plotted the takeover of the British ship, Margaretta a few days after the misunderstanding at Concord and Lexington. By the way, they did succeed, but they ran her aground. Bunch of farmers!

Pemaquid Point. They found hard evidence of a Norse settlement here.

If you want weather beaten faces, there are many old lobster fishermen along the coast.
