-27C by our outdoor sensor, last time it dipped this low the battery in the sensor froze. See what happens today. Wind chill -35 Brrrr really cold putting the garbage out this morning, the sunrise is beautiful, no warmth though. Sorry about leaving the back door open but now its frozen open so I am afraid the cold is going to keep on coming. Stay warm, think warm thoughts and say the appropriate to keep the furnace working. The Vermont castings stove is at the cottage no use here. Might turn the gas fireplace on just to help out. Well go to go drop the boss off at the bus stop and head to the coffee shop, read the paper. Some plumbing to do today, replacing the shower valve today.
