This was taken on Saturday, on the road out to the Pt Reyes lighthouse control of the SF Randonneurs 200K brevet:
There are several working dairy ranches along that road.
(this is a different location than that in the SF Gate story)
nice photo Jo! i love everyone just waiting around. Remember the cows all over Coleman Valley Rd on the Holstein 100... granted, I should have expected it given the name of the ride... but I was not stopping at that point!
