When I think of New England I think of Connecticut but mostly due to Mark Twain's story about the Connecticut Yankee....
The intent of my map was to show that New England is not a culturally significant entity of itself, it is not culturally unique, and nothing originates there by itself. You can't even prove that the term didn't come out of say, Buffalo, or Port Huron, or Green Bay, or Minneapolis.
If you can, I'll admit I am wrong. For the culture of these cities is as close to that of any in New England as you like. They use the same slang, have the same work ethic, enjoy the same hobbies, have the same world out look and POV, etc. Does the culture have a upper Midwestern flavor? Sure. But until you provide some proof of your unverified statement, we'll just have to agree to disagree. Just because you just think you come from a unique place doesn't give you license to go on a crusade, you don't.
All New Englanders seem to have some semblance of the same accent as is Boston or NYC blended somehow.
On the complete other hand the campus of the Univ Of Md at College Park seems to be the most non-accented place in the USA to me.
