It's 0 DegF right now here in Upstate NY. My wife woke me up around 1 am and said the power is out, got out of bed and it was cold in the house, went down stairs and fired up the kerosene back up heater, house temp was low 50's, checked the girls and the tent was 66, so wasn't worried yet. Went back to bed and 5 mins later power came back on, yippee, back down stairs to turn of the Kerosene heater and back to bed. Man I was happy the power came on.
