Dark - that's where the less savoury elements of society hang out. In the bush, that's when animals begin to prowl for their next meal. Dark - danger. But then on the horizon we see the first glimmerings of light. The animals fade into the background with the shadows.
Criminal elements slink away.
The light grows brighter, more intense. The world around comes alive. And with the growing light we see a most unusual sight. We hear laughter, and music, and the sound of many feet. It's a parade, coming this way.
