MOTHER -- I've noticed that too! There's also this dark / light / dark / light thing that seems to happen about every 3rd or 4th time I get hungry. Noticed that one?

DAVE -- Yes, I saw that. The price of oil and natural gas dropped. I haven't done it yet, but I'll bet you could build a "green business index" made up of companies like Vestas, and chart that with gas price per decatherm and oil per barrell and get curves shaped about the same. Sounds like good homework for ya Dave!
