Before and After Katrina

Check out http://maps.google.com.  Do a search for New Orleans.  Zoom in a little, then click on Satellite.  This will give you a view of what New Orleans looked like before.  Now click on the new red button they added called Katrina.  That will show you the exact same shot, except with new satellite images after Katrina.  Pretty crazy.  You can zoom in pretty far, too.  One of the places I zoomed into looked like a horse racing track with lots of horse barns around it.  Makes you wonder what happened to the horses...
