Chris Richmond, president of Moving Pillsbury Forward, explains the machine that grounds wheat into flour on the fourth floor of the AB-Mill, the former heart of the operation at the vacant Pillsbury Mills in Springfield, Ill., Nov. 30, 2023. The nonprofit Moving Pillsbury Forward is spearheading a $10 million plan to raze the plant and redevelop the 18-acre site. The mill operated under Minneapolis-based Pillsbury and another owner for 71 years but has been vacant nearly a quarter-century. (AP Photo/John O'Connor)
