Zay Harding visits Patagonia on Hwy 40. He climbs Volcan Lanin, visits the Lake District in San Carlos de Bariloche, the former Hippie colony of El Bolton, Cueva de las Manos (cave of hands), Mount Fitzroy and Cabo Virgenes Lighthouse. We see beautiful scenery. He has to fill gas containers as some areas of the road have no services.
