Our ambitious governor has signed a law allowing our illustrious mayor to install speeding cameras in school zones which, by the newspaper's calculations, covers roughly half of Chicago streets and will be operational as soon as July 1. The cameras will run from very early in the morning to very late in the evening M-F, well beyond what most of us consider normal school day hous. For those of you hobbying within Chicago proper, watch your speed in these zones. The last thing you need is a speeding (or red light) ticket showing up in your mailbox and having an SO find it. Imagine the questions that will draw.
