A sign advertises oil cleanup supplies for sale at Ship & Shore in Dauphin Island, Ala. Oil continues to spill into the Gulf of Mexico following the April 20, 2010 explosion of the Deepwater Horizon oil rig, fouling marshes and beaches along the Louisiana, Mississippi, Alabama, and Florida coastline. Tar balls have been found on Dauphin Island beaches, but so far the area has avoided more serious consequences. (Photo by Carmen K. Sisson/Cloudybright)
