Anne Alt, president of the Chicago Cycling Club, takes us on a tour of the Dearborn Bike Lane in the middle of a busy work day. (Courtesy of The Chicago Tribune). I agree with Anne's take on its importance in encouraging new, "non-aggressive" riders to bike downtown. There is also no doubt that enforcement of those driving and parking in the bike lane needs to be stepped up.
