People want to talk you when you drive the Chevy Equinox Fuel Cell. Today, for instance, in the hardware store parking lot, I met John Ross, of Ossining, New York, who wanted to know about the fuel cell Equinox and also wanted to talk about his Ford F-350 crew cab pickup, which he runs on used cooking oil. It seems that everywhere I go, I meet people who are excited at the prospect of alternative fuels. "Do you know how great it is to drive past a gas station and know that I don't have to stop there?" he asks. Well, yes, actually, I do.
