I have a bad habit of forgetting just how busy some conferences can be. My trip to Madrid was one of those. On the whole trip I had, perhaps, a couple of hours of free time. I took a whole load of pictures but as they were, technically, on work time and work-related I won’t be sharing them. However, I did spend my few hours free walking and photographing, and I’ll try to share some of those images over the next week.
