Enjoyed this book about the Tarahumara culture in 1970's as I was hiking this region at the time. The locals used Corn to make Beer (no bottling) and partied annually at each Ranchita to get the corn crop planted (25% of corn used to make beer for planting parties, baptism, cures, etc.) Much other reports on these short-fast-mostlyVeggie runners of the trails in Copper Canyon. We traded plastic drop clothes (roofs) for bear-grass baskets. Very friendly people to backpackers at that time. Hike to hot springs and below was TERRIBLE (waterfalls, etc). So get a NEW hiking book on this area before you go.
