While traveling to Chicago for a class that one of our daughters took earlier in the week, my wife was in the city for a total of about 15 minutes, was stopped at a light using the GPS function on her phone to find an address, was pulled over by a police officer, and was promptly given a $100 ticket for violating some ordinance about using handheld mobile devices without an earpiece.
As if the earpiece would have made any difference in mapping out the address.
Same 15 minute ride into Chicago to drop off my daughter at this class the following day. This time I drove and my daughter brought my camera. During those 15 minutes, my daughter snapped pictures of 10 different police cars, one tow truck on the prowl, and one traffic cop gabbing on her Bluetooth with enough tickets sticking out of her pocket to choke a horse.
Oh, and if you need to park for more than a few hours, it will cost you a cool $37.
