From National Geographic: Across our country's vast and untamed wildernesses, a hardy breed of American still lives a life set apart. They are not just off-the-grid, they are physically cut off from society by the Rocky Mountains, roaring rivers, and frozen tundra. But however self-sufficient...no man's an island. Sooner or later, these off-the-gridders need a life-giving tool - like fuel or bullets - or a life-saving essential - like food or medicine. When they do, they turn to the cast of Survive & Deliver. By packhorse, dogsled, powerboat, snowmobile or bush plane, this unique group of men risk all to deliver supplies where no one else can or will. Delivering their payload is a matter of life or death - not just for their clients, but for them as well - in their ongoing mission to survive and deliver.
