(Co-op News 3-1-2012) Students in a North Dakota school district now have a safe place to walk and bike to class, thanks to a Minnesota G&T. A donation from a G&T helped a North Dakota town repair sidewalks near a K-12 school. Great River Energy, Maple Grove, donated more than 1,300 tons of fly ash to the city of Washburn for repair and construction of sidewalks and trails, some of them located near its K-12 school.
