Members of the 145th Airlift Wing examine a rain gauge during an Environmental Education Day held at the North Carolina Air National Guard base, Charlotte Douglas Intl. Airport, April 18, 2015. Airmen received several tips including the recommendation to only use 1 inch of water once a week for your lawn. Several agencies participating in community programs relating to recycling, water quality and environmental restoration attended the event. Airmen were given the opportunity to learn more about local environmental initiatives within the community, at home and at work. (U.S. Air National Guard photo by Master Sgt. Patricia F.
