What, the one about the Klan controlling Indiana? They virtually did for a time, back in the 1920's I think. Then their leader got nailed on a rape charge and it all fell apart. But that was then and this is now. How can you say that the Klan's strongest presence is in Pennsylvania? What do you base that on?
Bottom line, PA, Indiana, Ohio, etc, the klan is powerful up north. Contrary to popular belief, the South does not have a monopoly on the klan.
