Well, employment would be a problem. Generally the jobs (and the voting block) center around the Burlington area, and most out of staters tend to settle there. I think the fact that Chittenden County is the most populous county (as Chittenden County votes, so votes the state), the most liberal by far, has the most personal wealth, and is populated these days in the majority by people from away...has a lot to do with the "us vs them" attitude. Civil union was a classic example -- it passed in the greater Burlington area and virtually nowhere else, but that was enough to make it law. But Burlington is one of the nicest cities I've been to if city living is what you want.
Your criteria (low development pressure) would rule that area out, though, as well as the southern counties and the interstate corridors -- all of which are becoming bedroom communities for long distance commuters.
As others have said, the Northeast Kingdom is feeling the least pressure from developers. And the natives really don't bite as long as you don't try to bring Boston/New York/Baltimore with you. I'm a California transplant. At first the locals stayed away. But when they learned I was a Marine, could shoot well, could handle a chainsaw, and didn't want to change a thing they warmed right up to me and now count me as a friend.
It's a great life up here on my hill with my wife, pets, and livestock. At certain times of the year the tourist pressure gets pretty hard to take (why must people park in the middle of the road, for instance, while taking pictures?), but get them out of their cars and most folks are downright decent. I think living in a big city folks tend to drive more aggressively than those in the country, and that rubs at times. We meet some great people from all over the world walking down our road, though, and have penfriends now in sixteen different countries that were met right here on our hill.
Good farmland is getting pretty hard to find, however. The best is in the valleys, and of course the valleys are the first to be developed. Hillside farms like ours grow mostly rocks, and as a result there are none of the large scale farms you see in upstate NY.
Heck, it's too hard to explain all this in a post. Why don't you just come up for a visit some weekend?
