A runner dodges zombies during the Zombie Apocalypse Fun Run and Youth Walk at the MPF track on Joint Base Andrews, Md., Oct. 30, 2013. Runners were given belts with two flags hanging from each side; the object was to complete a mile without the zombies claiming both of your flags. Zombies hid in the trees and waited for the runners to pass by. (U.S. Air Force photo/Senior Airman Lauren Main)
