In recognition of St. Patrick’s Day and in conjunction with the first signs of Spring, the Photo Challenge is wearing green this week. Michelle W. asks us to step back from the usual challenge and present a gallery of green. You can read the entire challenge post here. Of course, one of the first thoughts that came to my mind was the brightly colored collection of automobiles I see every year at the annual auto auction. The opening photo features a glimpse of a 1950’s era Ford Ranch Wagon. The small gallery of images below features a few other green machines.
