Go dark! Tomorrow – Saturday, 3-28-09 – is Earth Hour when cities, and businesses and tens of millions of people like yourself all over the world will be turning off their lights for one hour – from 8:30 to 9:30 PM (your time) –  in honor of saving energy to save the entire planet.

Join in – flip those switches to OFF and feel the powerful energy of tens of millions of others, like yourself, sitting happily in the dark, saving energy. Do it with a friend — it’s more fun that way.

Anybody who is anybody will be tuning in and turning off, according to the World Wildlife Fund, which has organized this delightful plunge into the dark. Nearly 200 cities in the U.S. are officially committed; 2400 cities in 82 countries have officially signed on.

Broadway theater marquees and other world-renowned landmarks will be turning off their lights:

• Empire State Building
• Rockefeller Center
• Chrysler Building
• Golden Gate Bridge,
• Space Needle
• Sears Tower
• Great Pyramids and Sphinx in Egypt
• Acropolis in Greece

For those of you with short attention spans who have difficulty reading past the first word “ Earth” and are confused – this is not Earth Day – it’s a little dress rehearsal. So if you are reading this after Saturday, and you didn’t get to join in the dark-hour fun, you can still make up for it to the gods of green on April 22, 2009, for the big Earth Day.

Turning off is a big turn-on.

Even the Las Vegas strip is turning lights off. And like Vegas, what you do during Earth Hour, stays in Earth Hour.
