I was on a lake in Kingston NH (which is only 10 minutes over the Mass border) all weekend and the Ice was 18" thick. While we were out there someone actually landed a Helicopter on it....was pretty cool.
"If you're arguing with an idiot, make sure he isn't doing the same thing."
Even central to nothern CT has plentyy of ice. I was on a few ponds yesterday near the coast which had 3-5 inches of black ice. A little thin , but it was fine.
