Old style wind towers. Taken on a road trip in an open topped car, Los Angeles to San Francisco, July 1991.
I was with two old school friends, Keith Hunt and Robert Williams. They could both drive so I was the backseat passenger who could enjoy the views. occasionally I would ask them to pull over so I could get out my Mamiya RB67 Medium format camera and photograph the sights.
These wind towers were beside the main highway in California, there seemed to be hundreds of them and we enjoyed driving the service roads to have a look. America really is a country of big contrasts, the congested freeways and the open wind farms were a lasting memory.
