Amtrak's Empire Builder Route ~Chicago~Minneapolis~Spokane~Portland

My first night on the train..Monday... After Amtrak's  last stop in Minneapolis..I was settling in to sleep.... pillow under my head, seat reclined, foot rest up... then came a strong thunderstorm. Strong winds, thunder, lighting, all familiar parts of the storm, but in a train...I thought, "What have I gotten myself into..." quieting my heart... praying... what else could I do...
