At 8:30, Julia and I turned out all the lights, lit some candles and called the family together for some piano, charades, and Apples to Apples. We tried to keep all of the lights off for the entire hour, but when Grant announced that he was going to have to pee in the dark, we made an exception and turned on the bathroom light!
I don't suppose that the amount of electricity that we saved by turning off our few CFL's made much of a difference in the world, but it's kind of like raindrops in a bucket... they add up. Maybe our electric bill will be a few cents less, but even better than that was the fun family time we had together. We had so much fun, that the hour turned into an hour and a half, and Julia said that we should have "earth hour" more often!
