This photograph is a tribute to the countless number of Americans who volunteer their services to fire departments and emergency response agencies around the country. This flag is painted into the grill of a firetruck in the fleet at Shell Puget Sound Refinery, where a community-wide response exercise was conducted Wednesday night. Shell, Tesoro, General Chemical, and Air Liquide make up the March Point Community Awareness Emergency Response (C.A.E.R.) organization. Each year dozens of emergency response personnel take part in an exercise that provides an opportunity to work together in response to a hypothetical disaster. Among participants are the Anacortes Fire Department and several local fire districts, as well as agencies such as the Skagit County Department of Emergency Management, the American Red Cross and Island Hospital.
