One more suggestion- if you do go to Acadia, for ~$120 you can drive your car onto a hydrofoil
Ferry that goes to Nova Scotia in under 3 hours. I've never been there, but my brother and
sis in law did it last year, and said Nova Scotia was really beautiful to drive around on. The Ferry leaves from Bar Harbor, which is right on the edge of Acadia NP. Has gambling on board if you're inclined, and I think they have a slower, sleep overnight version, get to Nova Scotia in the morning for the day.
www.catferry.com/General Genocide- Not meaning to diss the inland, I have in mind a local guy that is helping my parents (they're in their 80's and need help with repairs to their farm, as I live 4 hours away and can't get their
every weekend). I dropped off a payment to the guy just last weekend and he lives 3 miles down a dirt road, in a house with no TV, Fridge, or Phone. Just a kitchen table with a radio and a few cans of food. As I drove to his house I go by a half dozen abandoned houses.
Weird thing about Maine, alot of outsiders are buying up farms and converting them to vacation homes. A Citibank Lawyer from Hong Kong lives in the same town as the guy helping my folks, and has spent over $700K restoring a hilltop farm this summer.
