I spent much of this week in northern Nebraska, attending various events and staying at the Niobrara Valley Preserve. It rained much of the time, but I caught a break in the clouds Monday evening and happened upon the bison in our east herd as the sun was going down. I spent about an hour and a half tagging along with them as they moved slowly toward the setting sun. If you haven’t spent much time with bison, one of the things you notice immediately is how quiet they are. Apart from some contented grunting, the primary sounds I heard as I accompanied them was the crunching of their hooves in the grass and the sound of them tearing mouthfuls of food from the prairie. It was very peaceful, and provided the perfect accompaniment to the sun going down over the hills.
