Second honeymoon in Yellowstone. June of 2006. We were driving in the north entrance when a herd of horses escaped from the corral of one of the ranches. It was fun helping the ranch hands round-up the escapees. Later we were driving on the north-west side of the big lake during a summer snowstorm, when a small group of 6 buffalo decided to move from one pasture to another and use the road to get there. So this small group were moving in the left lane while I was moving very slowly in the right lane. It was wonderful moving with such beautiful animals.
