  • Agua Fria Open Space Alliance: Enhancing Community Life

    This is the Agua Fria Open Space Alliance (AFOSA) home on the Internet. We are a nonprofit organization located near the center of the State of Arizona, USA. AFOSA was founded for the benefit of the residents of the Town of Dewey-Humboldt, Arizona’s Country Town. We are concerned with the community quality of life, independence, and exemplary status among Arizona towns. We hold public events, write about the natural open space in and around our town, and work to build community cohesion and the town’s prominence across Arizona.
