SWEEPING CHANGES--With the Scioto River in the background; a worker sweeps freshly poured concrete steps in front of the future home of the Center Of Science and Industry, in Columbus, Ohio, on Tuesday, Aug. 31, 1999. COSI is scheduled to open its 320,000 square foot building on Nov. 6. The steps are part of the Columbus Rec. and Parks river front amphitheater. (JACK KUSTRON/photoj.com)
