Since this undoubtedly will fall in the middle of some critical March Madness game again this year, I would probably be putting my life in jeopardy by participating. (DH is quite the sports fanatic.) I will turn out all of the lights outside of the one we're in, though, but we pretty much do that every night. I've also replaced most of the bulbs in our house with compact florescents, so we try to keep electrical consumption at a minimum.
