Getting around Illinois

A tough city to drive in, Chicago has convenient public transportation, taxis are easy to come by, and many areas are a pleasure to walk through. The Chicago Transit Authority operates the “L” (or “El”) a system of elevated trains that run 24 hours a day. There is also a River Bus that runs during rush hour in the summer, and the city is becoming increasingly bike friendly.
