“Have Fries Will Travel”. The book is an adventure story featuring “Rock” an eco-rap singer (strangely, this rapper wears a cowboy hat). He buys Tiny, a smelly diesel car, at a used car lot. Rock soon has Tiny running on vegetable oil from Rock’s favorite restaurant. With Tiny’s exhaust smelling like fries, the two set off on a road trip to encourage others to use biodiesel in their cars. Along the way, they visit farmers growing soybeans especially for making biodiesel. Link.
