Biodiesel in Your Neighborhood

This weekend I went to look at a diesel Volvo station wagon with a friend who's shopping for a second family car. One of their desired features (though not necessarily a requirement) is to be able to use biodiesel, which is growing in popularity here in Seattle. But there is the concern about having to drive a ways (usually farther north in Seattle) to be able to fill up on the stuff. Well, worry no more with this biodiesel locator Google map (hat tip to Treehugger).
