A special moment at Yellowstone: This big guy, head begrimed with mud, had just finished swimming across a river, the bottom of his coat still dripping wet. He walked over to my car, stood there for a few moments, looked in at me, and then slowly trotted around the car to join his buddies. He was so close I could have reached out and touched him. Of course I was thrilled and quickly snapped this photo. The photo doesn't really do justice to the magnificent presence and immense size of the animal.
