White Smoke.

History fascinates me sometimes. How as we move forward technologically, certain rituals are so engrained in tradition that they remain the same. It's comforting, actually.

Humorous, too. The simplest signals can be so confusing.

Like the smoke at the Vatican. The people thought they saw white smoke, but it was smudgy. No one was certain, so they had to wait until they heard the church bells to confirm the announcement.

Like the lights in the North Church to let us know the British were coming. "One if by land, two if by sea..." The signal was too complex, so they had to wait until Paul Revere came to tell them in person.
