I have a story in the Monitor today about a program at a Rockywold-Deephaven Camps in Holderness that uses ice blocks, cut from Squam Lake in January, to keep food cold in “ice boxes”. You should check it out because it’s got great photos of hauling 110-pound blocks of ice to people’s rooms every morning:

When I was a kid in Virginia, “ice box” was still a common term for refrigerator; I used it and didn’t think twice. (Yes, we had electricity – it was northern Virginia and I’m not *that* old.)
