Figgy Frank, we have a thermometer in the hallway that gives outside/inside temps. and the lowest temp. reached until manually reset. This am it was -8 when I got up. The sleeping figs, dahlias, cannas and potatoes are in the basement but we don't have a gauge down there. If it would go below freezing in that area we would definitely know by the temperature on the main floor. Wind is picking up here. Now the cold really begins...
