Book excerpt: In addition to cannabis being sanctioned for medical use throughout the state, and recreational cannabis (which will be legal in 2018 throughout California), the largest amount of illegal marijuana in the state is found in clandestine trespass grows run by Drug Trafficking Organizations (DTO?s) on national forests, parks, recreation areas and wildlife refuges including state and local wildlands. However, there is an elite group of game wardens who hunt these cartels and risk their lives to keep America's wild places free.
