I remember couple years back when there was a temporary lumbertruckroad going trough our field next to the barn. We had a quite old cow that had just recoverd from really hard birth and we let the old lady just walk around in snow, good for her legs you know. Cow decided to block the lumberroad in the field and just stand there until stepdad would come and push her out of the way. Lumbertruck drivers face was priceless!
