The subforum regions are divided to include New England and Mid-Atlantic. I don't believe there is a designated "Northeast" region?
I believe the Northeast and Mid-Atlantic are not necessarily competing regions, but Mid-Atlantic states are contained within the larger Northeast, as are New England states.
Furthermore, I'll concede that some parts of New York could probably be considered New England, but there's no way I'd ever offend New Englanders by suggesting they bear responsibility for any part of the Garden State.
Is the system perfect? Maybe not. New York is a tough state to categorize because it's fairly big and arguably borders 3-4 different regions. I sympathize as a Pittsburgher. It's tough to know if our topics should belong in the Mid-Atlantic or Midwest category, but I do the best I can with the tools that I have.
