The sun was shining when I stopped my motorbike by an old tractor in rural Norway. 15 years earlier, I had worked on a machine just like it for my brother-in-law and I was looking forward to telling him about it at the kitchen table one evening in the future. At the same moment I remembered what I had seen and tried in Denmark, Germany, Netherlands, Belgium, France and England. My travelogue was getting too long for me to tell it over a single cup of tea.
