I just returned from W.Virginia helping an old timer harvest his string beans at his farm.A friend introduced us and a few others also went to help.Well I noticed a cord of oak in a shed and the conversation turned to wood burning.He said he was waiting for 4 more cords from some hunters who hunt his land in exchange for firewood.I said that's a good amount of firewood for down here and he told me that it gets down to -15degrees F during the winter that blew my mind.I had no idea it got that cold in the south.It doesn't get that cold in Boston every maybe -5F,So I apologize to the individual who I said out of ignorance that a drafty house in Virginia is not quite the same as a drafty house in Boston.In the hills of W.Virginia it's much more drafty.
