I am not intimately familiar with all of Vermont, but there is only one city of any size; to wit, Burlington. Brattleborough and a few other places are big enough to have centers, etc.
Vermont is the green Mountain state, and that name is quite appropriate, because there are these green mountains all over the place. There are corners in the North that aren't all that steep, and the hills aren't as high as the Himalaya, but from top to valley there are a lot of places with four to five feet in between (Well, I'd have to look at the details to be sure).
Then there is the matter of culture. There was an article in Yankee magazine, maybe a half century ago, that described how they froze their old folks for the winter. They'd store them on the North side of the barn and thaw them out in April.
But what do you want to know about Vermont?
There's someone who uses Brattleborough as the setting for crime novels. The main character is a cop, so I don't especially like the novels, but it gives a slight taste of the sourest part of Vermont. Then there is Bennington, location of Bennington College - The Secret History by Donna Tartt It is a widely known novel that was set at the college. Then there's Lake Champlain, where Burgoyne's army was slowed for months, thanks to the great Benedict Arnold, who defeated Burgoyne at Saratoga, N.Y.
It is a wonderful place. Go there and find out what part you want to use.
