Illinois Soybean Association (ISA) sponsored the participation of three Illinois companies in the Special Olympics World’s Largest Truck Convoy on September 20, 2008. The three companies, Double D Express, Peru; Hoekstra Transportation, St. Anne; and SS Chad Express, Sigel; each promoted biodiesel through their trailers wrapped with “American-Grown Performance” graphics, which the soybean checkoff funded earlier this year. Each of these companies volunteered their trucks and their time to help support the Special Olympics Illinois.
