Bev,
I am near Pittsburgh, Pa. We are most lucky here. Most bad weather splits and goes north or south of us. With the high of 3 come Tuesday and low of -11, well that only comes by every 10 years or so. Puts us back into zone 5 or 4 and we lose some stuff.
I am lucky to have a good family. My son put in a new heating/cooling system for us this last summer. The furance hardly comes on and the house is warmer than ever. He put a whole new duct work system in. The fuel bill is less than half of what it used to be.
