On the link they have a section to find biodiesel sellers. You have to drill down to the retail outlets but they list two one in Missoula and one in West Yellowstone.

It takes a lot of soy beans and other vegetable oil to make biodiesel. Besides we use a LOT of diesel in this country. Every railroad engine, every 18-wheeler all use diesel. Millions and millions of gallons. If you want to still eat, we just don't have the aerable acreage to grow enough crops to make enough biodiesel. Like I said, if we used all of the waste vegetable oil to make biodiesel, we'd only offset about 1-2% of the annual diesel used in this country.

Do your part and buy a diesel. You can then brew your own biodiesel and use it. There is more chemistry to it than most people think. The more non-commercial diesels sold will make it more economically feasible for the biodiesel brewers to go commercial. There are already standards for biodiesel.

Open up the link and find out some more.
