After an adventure that involved deer chasing, the dogs and I headed back to our house. Coming back through the woods I noticed the path the the dogs have worn into the yard over the years. I find it curious as it is not the straightest distance between two points but has a curve to it and no discernible reason for the curve - at least that I can tell. It was interesting to watch the dogs bound to the house in front of me. They were loyal to the path and to the curve. No deviation at all.
