While on a drive around Horsetooth Reservoir I came upon a herd of cows wandering in the road. Made me smile. They were willing to move to one lane or the other to accomodate passing traffic, but primarily they hung to the middle. (The car on the left was there first so they are crossing over to allow it to pass first...they seemed to have an inate sense of traffic justice. But maybe I'm anthopomorphizing just a bit).
I slowly followed them for a while before they took a sharp left turn and headed up the road toward the farmhouse where presumably they are fed and or milked.
