Join the Cystic Fibrosis Foundation for the Lawton Great Strides walk this June. Sign up as an individual walker or form a walk team, and bring the group to the Fort Sill Veterans Center for a day of walking for a great cause. After this one-mile walk, stick around for some tasty treats from the food trucks parked nearby. Feel free to bring the kids down to participate in some children's activities so they don't miss this healthy day of fun.
