The sky was very dark but it didn’t rain. We couldn’t find anywhere that sold Pontefract cakes but came across the Haribo factory (closed at the weekends) and, as we drove home, looping back on ourselves, the Ferrybridge cooling towers (some of which, I learned later, had collapsed in strong winds in 1965). In a shop, just outside the town, I was given a free batch of paper; in another, a knife sharpener. People are really nice here, my son said.
