INTRO-- One year ago today, a POWERFUL TORNADO swept through Granite Falls, killing one person and destroying homes and businesses IN THAT WESTERN MINNESOTA TOWN. The TORNADO, CLASSIFIED AS AN F-4 BECAUSE OF IT'S FIERCE WINDS, caused more than 20 million dollars in damage. Since then, residents have been working to rebuild their community. Dave Smiglewski is the mayor of Granite Falls. He's on the line now.
