Many years ago I had a cousin who lived in Lakeland Florida. He used to drive down to Tampa (about 30 miles) to enjoy the "night life." One night as he was driving back to Lakeland he came to a train crossing with the arms down. He stopped and watched the train go past and even waved to the flagman on the last car. After he drove off he suddenly realized that he had driven that road numerous times and there was no train crossing on that road. As he was driving slowly along trying to figure what he had seen, he came to a curve in the road and there was an eighteen wheeler broke down that hadn't had time to put markers out. If he had been driving his normal speed there was no way he could have stopped in time.
