On this episode of Lost Highways, we look at the mustang, the wild horse of American myth and legend. Though they're widely revered as symbols of untameable American freedom in the West, the reality of the wild horse in the 21st Century is far less romantic. From the long history of the horse's evolution in North America to the helicopter roundups on rangeland in The West, we'll follow the blurry line between the way we've mythologized horses to how we actually treat them.
