Looks like I stopped working on Wacker Drive at just the wrong time. According to Chicagoist, they are filming Batmobile street scenes down there currently. I think it would be quite cool to look out the office window and see the Batmobile running up and down the street. I'm guessing that they are doing this overnight, though, not during the business day so I probably couldn't have seen anything anyway. I will be looking forward to seeing this movie in a year or two and spotting familiar sights as Batman does his thing.
