Before It’s Demolished, One Last Tour Of Duluth Central? Now that the decision has been made to demolish Duluth Central on the hill, I think it's time to set up the last tour or two for the former students. This June marks 10 years since the final class of seniors graduated from Duluth Central High School, and I have seen red since the "Red Plan" was put into effect. My memory is that the school was closed because we didn't have enough students to have three public high schools and that Duluth Central was going to be sold, and it was a done deal. It wasn't a done deal.
