I think in the past Alex has said he’s near where I think that RT 302 marker is at the mouth of Bretton Woods.
Thats an insane set up for very cold mins... bottom of the river valley but elevated at 1500-1600ft... with close terrain rises to over 2,500ft on all sides, draining cold air into that pocket.
If you want to see summer frosts, that’s one of the best looking geographic set-ups you’ll find for massive radiational cooling. I bet the minute that little valley goes into the shade around sunset that open flat river basin drops 10 degrees in minutes.
Even people living up those small roads up at 1,800ft probably don’t see anywhere close to the temps that pool just a few hundred feet lower.
