An airman tries out the pedal car obstacle course while wearing goggles that impair vision. The activity demonstrated the effects of alcohol on the body and encouraged people not to drink alcohol while boating. It was one of many interactive and educational activities that were a part of the U.S. Army Corps of Engineers Southwestern Division’s water safety event at the McConnell Air Force Base Air Show and Open House Sept. 29 and 30 in Wichita, Kan.
