Graphic from The PeoplesCube, who recycle their tips from last year. Tim Blair has a roundup of world events: "For some reason, Chicago’s South Side isn’t often mentioned in Earth Hour previews."
Don't forget to call the pizza guy before the Hour begins. May as well make your meaningless hypocritical gesture in comfort. I guess that's why they do it close to an equinox and not in the dead of summer/winter...wait, you don't have to turn off your air conditioner, just your lights. Hell, this year you don't even have to make the supreme sacrifice of turning off your computer. Don't forget to tell your Facebook friends you're sitting in the dark by yourself because you care!
I'll be ironing some fabric while watching a DVD (which is probably what I'd be doing anyway), and baking cookies (with evil non-locally-grown chocolate!). I could drive around the east side noticing that none of the yuppie-hippie types have shut off their outdoor security lighting, but then I wouldn't get fresh cookies. My priorities are in order.
