I remember sometime in the late 80's we went 4wheeling around Christmas. The day we went it was warm. We were in shorts and tee shirts. Right at dark we got one stuck. I mean buried. The weather was nice so we decided to come back the next day and winch her out. The weather turned over night. It went from sunny and 70's to sleeting and 30's. The warm mud from the day before turned into cold slush. With plenty of shoveling and winching we got the truck out. At this point we were wet and freezing. So we did what any young and dumb crew would do. We turned on the heaters and went back 4wheeling.
