HumBus: The Local Transit Guide to Rural Humboldt County, California is a 100-page reference for navigating local bus systems. Both public and private rural transit systems are detailed for bus travelers--with and without bicycles. Social service providers and planners will also find HumBus useful for learning about how--with limited budgets--transportation systems work to cover a large geographic area despite a low population density. When compared to urban systems, Humboldt transit may be considered a step behind, but when compared to other rural systems, Humboldt transit's complexity is definitely a sustainable step ahead with keeping people connected to community services and to each other over mountains, through the woods, and along watersheds, in the northwest corner of California. HumBus is the result of community collaboration among Access Consultants, the Area 1 Agency on Aging (a1aa.org), and Redwood Coast Music Festivals (rcmfest.org).
