Some time around 1960 in SWPa. where I grew up , we had a bad winter. Two days in Jan. , that yr. , temp was -45. Since this kid had never experienced that , schools closed no busses , etc. I went hunting some of the thousands of crows in the back fields. Hunkered down in a creek bottom , a lone scout came over , and I blistered him with a trap load , he fell on the other side of the creek. Had to walk 150 yds.up the creek and back to retrieve the dead crow to use on the next day's hunt , as a decoy. 'Til I got to the crow's body , it was frozen hard . Couldn't believe that. 'Course , saying again , this kid had never experienced such cold.
