Largest Muslim communities in the US?

Tariqa's post got me thinking about Islam here in the US. Where are the largest and most active Islamic communities in the US? One qualifier is that it must have school(s) for kids through middle or high school.

I know that Dearborn, MI has the largest Muslim population in the US, but what about other places?

Also, if anyone has any first hand experience or knowledge of what it's like to live in these places, please share.

Big cities, I guess.

I've heard Chicago has some good islamic schools..
