Windmills, Old and New. Windmill farms have popped up on farmland in the Sacramento Delta. In some ways the modern giant structures are a blight to the pure, unspoiled landscape, but in addition to being useful and efficient in producing energy, they are beautiful. Graceful lines, clean in design and alongside windmills that are a hundred years older, they provide a stark contrast of how times change. These are the Winds Of Change.
