We've all seen the images of the spreading oil slick in the Gulf of Mexico, but it's hard to grasp how big it is.
To put it in perspective, I've superimposed the slick on the Chesapeake Bay, showing that it would cover virtually the entire estuary, almost all of the Delmarva Peninsula and reach inland to Charlottesville and Richmond in Virginia.
Moving it west just a bit would oil Washington, too - which might seem only just to those who think the federal government has been slow to respond to the disaster, AWOL on regulating offshore drilling or MIA in passing climate legislation to try weaning the nation from its fossil fuel addiction.
