Turn up the heat

Lately, we've been having some seriously cold weather, at least for NC. I know all you people up in the northeast and midwest are used to these kind of Arctic temperatures, but 22 degrees (the current outside temperature) is bone-chilling cold to me. Maybe we should get a gas portable heaters...it would certainly make things toastier in the house, where we have hardwood floors... SO COLD in the mornings. A portable heater would also be a good thing to have if the power went out, heaven forbid. We could shut off the back of the house and be pretty comfortable in the living room, probably.
