As I look at the presence of a subway transportation system as a defining element of a great city, I am struck by the fact that “metro” is the Spanish word for “subway.” No doubt arising from “metropolis.”
But it also means meter, as in the metric measure of length.
So how many metros did you take the metro?
Oh, why does my mind run off in these poco loco directions, anyway? Just like my newest novel.
