This goes back to my days as a Police Dispatcher in Philadelphia.

I received a 9-1-1 call from a man stating that he had just passed a tractor-trailer (parked) with a bunch of missiles on the back. It looked strange to him to see this truck just parked like that with nobody nearby. (Hey, don't fight, just send a blue-and-white.)

The police were sent to investigate. Sure enough, there it was, parked--a truck with a few missiles on the back of it.

The police began evacuating the entire area.

After conferring with the people at Fort Dix, it was determined that they had better come out to check on it. In addition to the military, there were also "who knows" how many other agencies called in.

While evacuating the area, the cops got to a nearby house and a man answered the door, apparently woken up out of a deep sleep. When the police told him why he needed to leave, he replied that the truck was his.

Seems that the trucker was transporting cement-filled dummy missiles to some sort of military show in New England, and was passing through Philly in the area where his mother lives. He decided to visit mom and to spend the night there before continuing on the next morning.
