Boom goes down town today

So I’m sitting at work just working away editing some photos. when there is a loud bang and the ground beneath me shacks. WTF i say to my self i go out side to take a look, and over yonder i see smoke coming from the post office, and hear fire engines coming closer. i run back inside the studio grab the camera, grab the zoom lens, and grab a CF card and start walking toward the crowd of people. to find out that a truck trailer was on fire and something exploded.
