This morning I drove to work and passed a _Pile Of Rubble_ at a construction site. Before this wakeup call, I had driven blithely past it, but now I realize that it could CONTAIN A BOMB!
Don't worry, folks. I swerved across traffic to keep my distance from this lurking menace. There was a traffic accident, and it turned out that there wasn't a bomb in the pile of rubble after all, but I expect the construction company to pay for the injuries and damage. In this post 9/11 world, we can't be too careful.
