The Dark Knight is stalking my city

Those who know me are familiar with my preference for the blue-eyed alien in blue tights with a red cape, but for the past few weeks my city has been taken over by the other superhero, the dark and mysterious furry mammal. His nemesis Joker has been spotted in his purple convertible just outside "Wayne Industries" - the Board of Trade building in Chi-town. Now there is a burnt up helicopter under the rails of the "EL" at the intersection of Madison and Wells. I take it, there's a crash in the movie :-) Its very fascinating, there are rumors of sightings of the batmobile and the batcycle. I am going to try and hunt them down one of these nights. Maybe i can catch a glimpse of the Batman himself. (I know where he lives), the batcave is Lower Wacker drive..
