Rochester MN is clean and geeky (Score 1)

Rochester, Minnesota apparently also has an abnormally high rate of autism and asperger's (This comes from Autism discussion lists and Wired's "Autism in the Silicon Valley" discussed previously here - I have no links to research). IBM has a large facility there and there also is the Mayo clinic. The air is clean, but a lot of geeks live there.

Some parents are blaming everything from fluoride in the water, Mercury as stabilizing agent in shots, and measels virus from the MMR.

As a biochem grad student with a child on the spectrum, I can say that the current state of research is abysmal - at best shots in the dark based on heuristic arguments and hearsay.
