Grew up in MN, it gets chilly in NH, but I have never blinked here and had my eyelashes freeze together here. You will do fin in NH.

It’s a little backwards for the NE, look at taxes for the area you are considering, we are childfree and chose a high tax area with a good school for resale but if you homeschool I’d look for a cheaper area.

Politics here are pretty quiet, we have right wing idiots up here that like to fly flags on trucks and some of the idiots still have Trump signs up, but 95% of the NH folks I have meet since 2014 are decent.

Good luck!
