Show Me MO Tours, became green in July of 2005.  Our Excursion now runs on waste vegetable oil, thanks to the mechanical experts at GoldenFuelSystems.com formerly Greasel.com in Drury, Missouri.  Thanks, also, to Taco Circus in St. Louis and Boos Market in Potosi for providing the oil.  Our vehicle, when running on vegetable oil, is Eco-friendly and produces extremely low emissions, thus not contributing to global warming.  Below are some photos of the conversion process (click on the picture to zoom-in).
