I recall one visit from the mid-1980s: I used frequent flier miles, took vacation time from my job, and bought 4 or 6 rolls of film. Stayed with a friend at a FOAF’s apartment above a bakery, so we woke to warm sweet smells daily. While my companion worked all day, I mostly walked (and rode the Metro), taking pictures of windows, streets, architecture, people, and light. No obligations and no requirements.
