As others have said, Concord is a common demarcation. But in conversation, Southern NH often refers to the part of NH that has a lot of Boston commuters, or at least folks that commute to Massachusetts. By that standard, I would say start at Hollis, draw a line up to concord, then over to the Maine border. That area is kind of what i would call Southern NH. I definitely don't think of Hinsdale or Keene in that description.

This chart is definitely poorly sourced. Minnesota isn't even in the top 5 for tornadoes frequency or intensity.

Yup, totally. He can fuck all the way off, but only a total monster would be opposed to your struggling neighbors getting a meal, regardless of money source.

You cheeky devil
