Staff Sgt. Hunter Neutzling, 28th Aircraft Maintenance Squadron B-1 crew chief, completes an “S” curve turn during a beginners motorcycle safety course on Ellsworth Air Force Base, S.D., May 3, 2013. The “S” curve exercise helps riders learn to shift their weight on the bike which could help them avoid hazardous situations later on the road.
