At the end of a long research project: we've logged something like 20,000 miles in the air so far, and that's before the two trips out west to present our results. I want to do a full-on Jan Chipchase and post about the pleasures and terrors of doing user research far from home, but for now I'll leave you with this vivid warning sign from the Milan subways. Never attempt to have sex with the train doors, people, and have a good weekend.
