Woke up this morning to a brisk 16F. Third day in a row of below-freezing temperatures. Certainly not as low as the 2F reported by son Chad in Johnston, IA or the 3F experienced by brother Larry in Byron, IL but cold enough to create trouble. We discovered our water pressure reducer was the primary contributor to our frozen water supply, so that link has been removed temporarily. That and the overnight-dripping-sink method ensured flowing water for coffee this morning (french press Christmas blend).
