Are you celebrating, or have you celebrated, Earth Hour, tonight at 8 o'clock?

To support efforts to reduce Greenhouse Gases, and their possible effect on Global Warming, The World Wildlife Fund is sponsoring the awareness campaign all over the world tonight.  Between 8 and 9 PM, all many private and public buildings will go dark in support.

Most McDonald's Restaurants plan to participate.  Many well-known buildings, and government complexes, as wll as hundreds of private businesses, will get involved.

Here in Chicago, the famous Sears Tower and John Hancock Buildings will darken at 8 for an hour.  So will the Merchandise Mart - its 4.3 Million Gross Square Commercial Feet still make it the world's most spacious commercial building.

Marquee lights in the Chicago Loop Theatre District will go dark to participate, as will the iconic Navy Pier Ferris Wheel, and famous Chicago Water Tower.  Even the Statue of Michael Jordan, in front of the United Center, where the Chicago Bulls play their home games, will dim in support this evening.

Anything you or your family are doing in support.  Perhaps throwing around a glowing Frisbee, as students are planning tonight at the Illinois Institute of Technology?  Or, a "dinner by flashlight?"

Perhaps even a little extra romance - lighting barely needed here!

If you're using anything with a flame, however, be careful.  It's pretty windy outside tonight - and you know what happened here in 1871, at the alleged instigation of Mrs. O'Leary's cow.

Enjoy, with reflection!
