The revolution will be mapped

To get to the headquarters of the Cedar Grove Institute for Sustainable Communities, visitors have to navigate a lengthy dirt road past white picket fences, grazing horses and a variety of outbuildings in various stages of disrepair. Set in a one-room former Primitive Baptist church on a 43-acre spread in rural Orange County, N.C., the institute holds a collection of old, ergonomically incorrect wooden desks and metal filing cabinets. The only signs of modernity are computers atop the desks.
