migration mapped

I usually don't like to put up a post that simply references someone else's content.  As an architect I like to think of myself as someone who creates content.  However, this map on Forbes is so amazingly cool that I had to pass it along.  Go to the map, click on any county in the United States and you can see the immigration and emigration from that county.  Most importantly you can view where folks are coming from and going to.
