Established by three sustainable agriculture advocates who wanted not only to develop their beautiful [pie-shaped] wedge of land into a thriving food source, Pie Ranch also offers hands-on education for city youth in the origins of the things we eat. Pie Ranch, located just south of San Francisco, is one big sprawling source of ingredients for -- that's right -- pie. They grow wheat for crust, and fruit and vegetables for filling, raise chickens for eggs, goats for milk, and bees for honey. School groups trek down from the city to try their hands at planting, weeding, and milking, and get an education about the benefits of their local foodshed to boot. [Pie Ranch]
