I'm eagerly awaiting the 8 o'clock hour of this Saturday evening, which has been dubbed Earth Hour, as I recently reported. The dimming of lights for one hour in more than two dozen cities around the world is an elegant protest against wasted energy and light.
I welcome after-the-fact reports and comments from readers in all participating cities. What was your Earth Hour like?
