Wolfsburg I guess you're right at that. I opted for the sole mad scientist Nazi because as unbelievable as it is, there is a bit of truth to it, if anecdotal. There are a number of villages, one in particular (though I forget the name of), at the southern tip of Brazil and into Paraguay and Argentina that has a baby-boom generation that are taller, blonde-haired and light-eyed and look unlike anyone else in their village. They said as children in the 50's and 60's, a kind old man who said he was a government doctor went around administering polio or malaria vaccines and inoculated entire populations. It might not be a Nazi scientist or anything that fantastic, but these people and their stories exist and that's baffling enough without considering the implications.
