Yes it is... I'm one hour from Boston, so the "city" part of Maine (7 minutes to the NH border). But I'm told that Maine is now the most rural state in the entire 50, even including Alaska. If you go up north 6-7 hours from me, you enter "townships", yes, small blocks of land that if you squat on them for 7 years, they are yours (as long as the paper co's dont kick you off first)... and the number of people per sq mile is less then Alaska! Goes to show you what some crude will do the artic tundra!
Best time to come up here is mid August (absolutely perfect weather) or fall, nothing like it...
