Its 14 feels like -3 here in northern Michigan. Funny how it's so close huh.. Good to hear your staying warm, maybe try hanging up blankets/plastic over the windows to help with your furnace staying on. Do the same thing if you have a second level, try and seal it off best you can. Close doors to any extra rooms not being used... idk just trying to help, Im doing those things and it really helps. Hope you have a great day Patriot, stay warm, stay safe, and Merry Merry Christmas to you.❤️🙏
