Not many. We rode Minori’s car in St. Louis, buses and cabs in Buenos Aires. Miami… I got to see downtown only once! I also realized I rode the Muni and the cable car in San Francisco, but not the Bart.
I’m not that keen on trains. I’d rather ride a car or a bus, it feels much more like you’re inside the city, part of it, and not in a parallel tunnelway which magically takes you from place to place. However, the San Francisco Muni did feel like a bus, somehow. Oh, San Francisco, I miss you so much!
