San Francisco is one of the most "progressive" (read: liberal) cities in the US. And, as this NY Times article describes, there's a movement there to modernize Islam, at least in a small way.

As part of renovations to the Darussalam mosque in San Francisco last fall, a wall separating the women worshippers from the men was demolished and not reconstructed. This was the result of a campaign by what the Times calls "a small if determined band of North American Muslims, mostly younger women," to change practices they feel are discriminatory, and not a necessary part of Islam.
