Today was a pretty tranquil scene in Philadelphia. Although parts of the city resembled a sort of soft military occupation – police, uniformed soldiers (who were polite and helpful), TSA and border patrol (who weren’t), it was actually quiet in the absence of traffic and with a lot of people staying home from work. In the morning, people seemed to confine themselves to sidewalks out of habit, then gradually during the day, they fanned out into the streets.

Contrast this with what is expected tomorrow…

Okay, so that’s the Philadelphia scene from World War Z… which was actually filmed in Scotland with some Philadelphia landmarks photo-shopped in.
