U.S. Air Force Chief Master Sgt. Christopher Ostrom, 52nd Civil Engineer Squadron Fire and Emergency Services chief of operations, and his family spend time together while participating in a six-kilometer walk around Spangdahlem, Germany, May 29, 2020. During the walk, kids may find an “Eifel stone,” a painted rock, to take on their next adventure in the Eifel region, or they can bring a painted rock from home and place it somewhere during their walk.
