I have to say that living in DC can be a blast especially when a movie or TV series is filming in the area. There's an existing e-mail/text system that alerts citizens of which roads or bridges are closed or blocked on certain days and hours. Just like today, we got an e-mail alert from The Metropolitan Washington Council of Governments Office of Public Affairs stating that:
"Simulated Explosion: The Metropolitan Washington Council of Governments Office of Public Affairs advised that there will be a simulated explosion on Wednesday, March 25th, between 0930 and 1200 hours near the Key Bridge in DC that will produce a 20- to 30-foot fireball that should last approximately 2 minutes."
According to Reuters.com, this simulated explosion is going to be used for a new CBS action series called "Washington Field." I have not heard of this new pilot, but I am quite excited to see this fireball.
