The winter parking ban goes into effect today. No parking on designated snow routes between 3 and 7 AM. If you do, you're looking at a $150 towing fee and a $50 ticket. And do you really want to tangle with Chicago tow trucks right about now? No, you don't. Also be aware that there's another parking ban that goes into effect for the 500 miles of Chicago's snow routes, barring people from parking on them when there's at least 2 inches of snow on the street. $30 ticket for that violation.
