I dunno; I went to fireworks shows as a kid (...and my wife dragged me to Chicago's show last year), and I've always left feeling a little disappointed. For all the hype around fireworks, it's just not that interesting to me. Given a choice, I'd rather go to a museum, read a book, play a video game, watch a movie, almost anything else other than deal with the drunken crowds and the traffic.
Given that, I agree that it would be a lot more fun if fireworks display actually involved blowing stuff up. Maybe Chicago could combine urban demolition with fireworks, blow up abandoned/condemned buildings instead of just making pretty lights in the sky? Heck, how 'bout some "naval training exercises" out on the lake, complete with arial bombardments and SAMs? That would make for a much more interesting show.
My real ire is reserved for all the people who have their illegal fireworks that choose to set them off for the whole fucking month surrounding 4 July, usually sometime between midnight and three AM. Seriously, some of us have to work. Do that after dusk, but before 10PM please. (At least it's not gunfire though.)
