Greg Lumsden, a Cargill product line leader, gave a "macro overview” of grain markets at a recent event sponsored by the St. Louis Agribusiness Club at Cargill’s grain elevators in East St. Louis, directly across the Eads Bridge from downtown St. Louis, Missouri. About 70 members gathered to hear the overview, plus an update by the Army Corps of Engineers on the progress of work on an expanded 1,200-foot lock at Lock & Dam 25, upstream from St. Louis.
