 And the Renegade and Excalibur roller coasters at Valleyfair Amusement Park are back open after being temporarily closed due to flooding. Officials say the rides reopened following rigorous safety inspections. Valleyfair's parking lots were underwater when the Minnesota River crested in Shakopee in late June. On-site parking has since resumed. The 4th of July fireworks were postponed because of the high water in the park.
