Radio piece: Biodiesel for truckers

Here's a Living on Earth audio spot (including a transcript) about truckers and biodiesel; snippet:

"I didn't know a whole lot about it as far as biodiesel but the truckers say you get better mileage, the exhaust is not hurting your eyes or anything else. It's beautiful stuff. And so the truckers convinced me and, you know, that's who's gonna put it on the map anyway."
...

"Many truckers feel a tie to farmers because they transport agricultural products. And so far, biodiesel is not allowed to travel by pipeline. Instead, it's hauled by rail or tanker truck, so it's a source of work for truckers, too. The National Biodiesel Board ranks trucker outreach as one of its top priorities."
