Speaking of shopping, if you're thinking about spending time on Michigan Avenue from Wacker Drive to Ohio Street anytime between Monday and Wednesday morning, the street will be closed to vehicular traffic in order to tape Oprah's new season kickoff. If you want to get in on the O action, the show will begin at 5 p.m. Tuesday and will be free and open to all. You can scope out the best seats ahead of time by reviewing this map [pdf] of the event.
