just to give credit to photographer, but the point being Detroit could have a commuter rail run right up the middle with a "Michigan left" for cars after the train passes. Entrances/stops at intersections for passengers on the line, no need for extra road construction, no lack of driving lanes...I know Deeeetroit can do it.:rolleyes:
