I was drifting down an easy hill at 30mph with three six axle engines and 100 loads at O-Dark thirty one morning. I was looking out the side window contemplating life when the conductor said "cow". In the headlight was a black bull standing between the rails sleeping with his rear to us. He was nearer the left side between the rails so when we smacked him he disappeared off in the moonless blackness. The next day we caught a Westbound on the same track so we stopped to look for him. He was upside down next to the fence in the brush but still in one piece hoofs in the air. The only noise when we hit him was the drawbar slamming against the pocket. JP
