Its cold here too..frost warnings...i dont keep my room too hot. I wrap myself in a blanket while on the recliner
As a child we used coal to heat the house and then converted to oil. We heated with natural gas when married.

I dont ever want to give up indoor plumbing..i dont know any other way of living. When i was a child we would visit my dad's family and it was a small coal mining town. Some of their homes didnt have indoor plumbing. I remember not liking outhouses..lol
