Ten volunteer company grade officers pose for a picture after picking up litter as part of the Adopt-A-Highway program Nov. 7, 2011, in Tacoma, Wash. Per their agreement with the Washington State Department of Transportation, the company grade officer council is required to pick up litter on an assigned stretch of highway four times a year for the next four years. This opportunity allows members of the council to consistently take care of the earth, serve the community and promote a good cause. (U.S. Air Force courtesy photo)
