Do you live in a rainy part of the U.S.? Recent research shows that kids who live in the Northwest's wettest counties are more likely to have autism. But it's not clear why. No one knows exactly what causes autism, but doctors do agree part of it is genetic.

They also think that something in the environment and maybe even something in the womb can trigger autism. So what's with the rain? Here are some of the possibilities:

What do think about the results of this study?
