it s been one outcome from the largest private land donation in history to create a conservation project on a vast scale. myjourney to its heart takes me six hours in a 4x4. so, we ve blown a tire and, as you can see behind me, the road is pretty rough. we ve hit one of these huge potholes and i guess that s part of the story of tourism here. you know, the infrastructure is still a work in progress. but, fortunately, all the locals have been super helpful. for two american philanthropists, doug and kris tompkins, the route of parks was just one part of a decades long project in both chile and argentinian patagonia. over the course of 30 years, doug, kris and the tompkins conversation 0rganisation bought 2 million acres of land across chile and argentina.
