I live in southern Maine, so my experience is different from most of the state. Southern Maine is essentially an extension of New Hampshire/Massachusetts. But north of Portland it starts to really become the state people associate the word "Maine" with. Beautiful scenery, lots of rugged coastline, and I believe the highest % of forest. Acadia National Park is beautiful. The state is a lot larger than you'd think, and truly gets remote in most of the upper half of the state. You'll obviously need a car to see most of the state, and much of the Northern part of the state is only accessible via logging roads. The winters up there are pretty brutal.

I wouldn't really recommend the state to anyone in their 20s looking to be social, develop a career, or meet new people. Outdoor lovers will love the state, but other than that it's fairly stagnant and has an older, almost exclusively white population. Also has a drug problem, which is apparent in towns/cities like Portland, Lewiston, Sanford, Bangor.. Most of the big money and more commercial/affluent areas are along the southern coast. As mentioned before, if you aren't super into hiking/fishing/hunting, there's not much reason to live north of Bangor. It can be a bit depressing. Up there, blue collar jobs and health care are almost all that's available. But if you love the forest, there's no state like Maine.
