Interactive map of U.S. migration patterns

Forbes has created an interactive map visualizing migration data into and out of US counties. It's based on IRS data from 2008. The black lines represent people moving to a certain place, the red lines are people moving out. This map shows San Francisco — a lot of people moving across the country to get here — and after the jump is Hudson County, New Jersey (where I used to live).
