A Boy Scout asks a question during an informational briefing conducted by a member of the Civil Air Patrol while at the 2011 Selfridge Air Show and Open House at Selfridge Air National Guard Base, Mich., Aug 20, 2011. Boy Scouts from around the Detroit region were able to camp at the base for two nights during the show, work on their aviation merit badge and meet with cadets from the U.S. Air Force Academy. The Scouts also provided a variety of volunteer assistance to show organizers, such as helping to pass out wristbands to show visitors. About 200 Scouts participated in the event, with more than 180 completing the requirements for their aviation merit badge. (USAF photo by TSgt. David Kujawa)
