Don't panic over the U.S. National Whitewater Center's green river. It hasn't been flooded with toxic chemicals, just a little dye that went a long way in celebration of St. Patrick's Day. During Saturday's Green River Revival, there will also be a PowerBall race and live music by Larry Keel and Natural Bridge and Chatham County Line (pictured). Free admission ($5 parking fee). 1 p.m. U.S. National Whitewater Center, 5000 Whitewater Center Parkway. 704-391-3900. www.usnwc.org.
