The band was about to embark on their first concert tour in a van they converted to vegetable oil, using a kit they bought at GreaseCar.com. They paid about $1,400 for the kit, and their bassist installed the fuel lines, so they didn't have to pay for it.
I caught up with them again last night after they came back from tour. The van broke down, thanks to trying to haul six people and a whole bunch of gear on 12-hour drives through the southern heat. It appears the breakdown had nothing to do with the veggie-oil-as-fuel, though, so that's good.
They also learned the hard way what a lot of artists learn the hard way: Book with a map (ahem, Seth?). Just because you can drive 12 hours in a day doesn't mean you want to play a show, break down, get in the van, drive to the next place, and get 2 hours of sleep before you're back on stage.
