Just before dawn Christmas morning. One degree but no wind. We have seen wind chills down to -30 degrees and still been comfortable inside. The thick cob walls are very sheltering and the house is very tight. Our wish list for the future includes a more efficient wood stove, more insulation around the foundation, and ground that isn't covered with ice! Getting to the house has been a tricky trek, but we should have some thawing in the next few days. Merry Christmas.
