Very early on January 12, I will board a plane in Sioux Falls, South Dakota, and that night I will be sleeping in a hotel in downtown Lima, Peru. That will be the first of 21 nights in the Drug War Chronicle's Coca Tour 2007, which will take me deep into the indigenous Andean coca heartland (but not to Colombia, where, for the most part, coca production is not tied to ancient tradition but to the global cocaine market).
