"On Saturday evening, it’s "Lights out San Francisco," where people will voluntary turn off lights for an hour. The aim is to raise awareness of light pollution and the energy wasted by lights left on." (CS Monitor) Thanks to Steve Ghent for the link!
Hi Geri, boy I hope this idea spreads, I know in my area it is brighter at night than during the day due to all the lights. Thanks, Ed http://www.brightmoment.com
