Coldest recorded temperature in Ky. , Jan.19, 1994 at Shelbyville. 37F below. Milking around 70 Holsteins and dry cows and other stock around 150 head total. Animals in three different locations and cleared 20+ inches of snow on county and state roads to get to them. Using two 4240 JD tractors, mixture of #2 and kerosene. Never shut engines off 3 days. Cleared roads for Rural Electric trucks to get to problem locations. Did not lose any animals nor dump any milk. No cell phones back then either. Learn a lot about your neighbors when times get tough!
