Meet military-trained Dave Canterbury and naturalist Cody Lundin trained survival experts featured in this series. Together, Canterbury and Lundin take on some of the planet s most unforgiving terrain to demonstrate in their own way how the right skills and some creative thinking can keep you alive. Dave Canterbury joined the U.S. Army at age 17, eventually becoming a Special Reaction Team (SRT) instructor and sniper.
