Well, I used to live in Pittsburgh. I can't verify Pennsylvania has the numerically largest Klan representation among all the states. I can verify that it has a very strong klan representation. The klan has demonstrated on the steps of the Allegheny County courthouse in Pittsburgh and their were frequent klan rallies in rural southwestern PA, with the cross burnings and the whole ball of wax. Given the magnitude of Pennsylvania's population, it is quite plausible that they have the largest number of klan members.

I will be the first to acknowledge that the Klan and other White supremecist organizations are well represented on both sides of the Mason Dixon Line. But I'm asking for documentation that the Klan is stronger in Pennsylvania than in, say, Texas.
