that carbon-neutral hummer
Ok, Jill (see comment) -- that could be true! Of course there are biofuels & biofuels, but that's another subject!
I have just been doing some research on "carbon offsets" (I'll post the story soon) and was already thinking if I'd heard the phrase "carbon neutral" one more time I'd scream, and then seeing it on a Hummer was too much. Why didn't the guy just say this car runs on biofuels?
