Classes start tomorrow at Edison High School in Minneapolis. A summer flood did millions of dollars in damage to the northeast Minneapolis facility. But school officials say an around-the-clock repair effort and an outpouring of help from volunteers will allow the district to open the doors on schedule. Minnesota Public Radio's Dan Olson has more. Volunteer Gloria Sat, an Edison graduate from the l980's, didn't wait to be told where to go or what to do. Finding no one at the volunteer desk, she walked until she found someone who needed help organizing a classroom. Sat says many neighborhood residents are Edison grads and have a good feeling about the school. tape . . . i live northeast, it's our school we're hear to help out.
