More Than Meets The Eye?

Yesterday I spent the day/afternoon/early evening in downtown Chicago with two of my friends and their German friends. Well, I guess the Germans are my friends too. "Strangers are just friends you just haven't met yet." They're here visiting for three weeks or so. But besides the accents, I couldn't tell they were from a foreign country. They being named Hannah and Maria. Just so we're clear. Apparently languages are a big priority in the schools in Europe, so the girls speak German, English, Spanish, a little French, and Latin. Yes, Latin. That dead language. Meanwhile, I'm starting year four of Spanish at age 15. Oh, Europe. But I digress.
Anyway, we were downtown. Now, bear with me here because my grasp of geography is tenuous even in places I know well, so these descriptions may be slightly to totally wrong. As I believe, we were crossing the river onto Wacker. Previously we had to adjust our route quite a few times because Transformers 3 is filming in that area. I had just assumed they didn't want anyone messing with the sports cars or trailers or whatever. I'm not a big fan of those movies. They seem....dumb to me. I don't know, I'm no critic. Someone else can articulate that point for me. Little did we realize that they were actually filming. Go figure.
As we're crossing the street, I hear a large percussive sound. Maybe concussive sound was more like it. Regardless, it was an explosion. I wheeled around and there was a huge fireball reaching 30 feet in the air. The smoke lingered for a few minutes as the fireball withered and was replaced with the sound of gunfire. This might be creepy, but the sound of bullets being fired sounds awesome when it echoes off of the Marina towers and Hard Rock Hotel. It was very cool.
Stopping to see this nearly made us miss the train, but you can't exactly keep walking while a car is exploding behind you. However, we decided that if we had been a few minutes behind and hadn't known about the crew, we would have given up on the train and just ducked for cover.
Basically, despite feeling like an idiot, I really enjoyed that explosion.
