Not counting Alaska, which state extends farthest to the north?

Uh.... Maine.

North Dakota.

Nope ,that would be Minnesota (the Angle Inlet of northern Minnesota at 49°23'N is north of the 49° boundary between the U.S. and Canada and well north of any point in Maine, no matter how the maps looks).

BTW, I remember this was asked before, maybe at the beginning of A.P (like 2 years ago)but couldn't find it.

You are right, Mozart, this, and several other questions have been asked and ansered before. Those posts, however, are Archived, and, while they can be viewed, they are not "Live" (They can no longer be replied to.), and take up less storage space. The down side is that they do not show up when one uses the search function. All I can tell you right now is that the problem is being looked at. In a few months, I will delete all the newer duplicate questions. That may not stop them from being asked again, but it will cut down on additional storage.

Correct Mozart. DG. I tried to find if it had been asked but it didn't come up.
