saving the planet...one light switch at a time

So I participated in my first Earth Hour today. I dutifully turned all the lights off and dug out the flashlight my dad made me buy freshman year of undergrad "in case of emergency." I then proceeded to read chapters on the evolution on the printing press for class with my flashlight before I got a headache and just sat in the dark for the rest of the hour. But hey, my heart was in the right place. We'll ignore the fact that while I sat in the dark, one of my roommates proceeded to turn and then leave on every other light in the house. I will try to coordinate that better next year....
