interlude: meme: metro collection

The logos of all the metros that I can remember riding, courtesy b3co.com. In chronological order by first ride.

This set is pretty visually diverse, but if you look at the site, over half of them are stylized Ms. I'm no world traveler; they've got 151 cities. Also, I feel a little weird counting separate systems in the same city as different; also also, San Diego ought to be on there but isn't. (We've got a trolley. It doesn't go underground, but neither does the Berlin S-bahn.)
