I absolutely cringe when I have to take the subway in NYC. Homeless people in the stations and sleeping on the seats on the trains, rats sometimes even on the platforms, open drug use, erratic behavior. It’s a horror show. Then when I’m in London on the Tube, it’s so civilized. Seats upholstered in fabric, and signs to keep your feet off the seats. Of course, it is more expensive than the NYC subway, but it’s worth it. I’m used to the Metro in Paris, but it sometimes does have its issues similar to those in New York with the homelessness and erratic behavior. Also love the Metro in Montréal and the subway in Tokyo, the one time I was in the Japanese capital.
