A cyclist checks the light accessory on his bicycle before participating in a bike ride during National Bike to Work Week at Barksdale Air Force Base, La., May 17, 2016. Members of the Barksdale Cycling Club welcomed all cyclists in an effort to encourage more riding on base. Some benefits of cycling include increased physical fitness, lower stress levels, lower transportation costs, it’s environmentally friendly and an opportunity to enjoy the company of friends while appreciating the natural resources Barkdale has to offer.
