Holy crap. I had no idea that there were so many. Qualifying cities had at least one overnight stay, except Hong Kong, Pittsburgh and Detroit, where I spent most of a day and then escaped before night fell. Actually, I'm kidding; I really loved both of those cities, which is why I wanted to put them on the list. * indicates that I visited the city multiple times, usually in totally unrelated contexts.
