Imagine working eight hours every weekday in Columbus but living in Chicago or Pittsburgh and being home each night in time to walk the Magnificent Mile or chow down on the Steel City's Primanti Brothers sandwich topped with coleslaw and fries — after a 30-minute or 15-minute commute. Yes, a 30-minute commute in a tube to Chicago or 15 minutes to Pittsburgh at over 700 miles per hour.
