[Rain Man]

Glad no one was hurt. Those types of things can kill people.

In the early days of our company, my wife and I were doing seat belt observations on a street corner in Colorado Springs when a disembodied tire came rolling down the road. We watched it roll by at relatively high speed and that thing went forever. It probably made it another quarter mile before it fell over. Eventually some dude came in search of it, but we never even saw where it came from.
