more info on biodiesel
This guy has some great FAQ about biodiesel, and I just found this other site, that I wish I'd seen before my trip: a map of Nationwide Biodiesel Retail Locations! Then again, neither the SF or Berkeley locations are on there... so it's probably best to note there are more locations than you think!Oh, lastly if you're looking to learn more about what this crazy biodiesel stuff is, check out Wikipedia!
