Buenos Aires Subte

JG: Soon, very soon, we will upload a deluge of photos and videos from our 5-day trek to and through the Salta and Jujuy regions of northwest Argentina.

Until then, please enjoy my trek through the entire length of a Buenos Aires subway train, the open, accordion-style subte of the H line here, with no doors. (Coming to New York City soon.)

I've wordlessly walked the length of an open subway train once before, in London, and I find  that the activity offers an opportunity to ponder human society and the nature of existence.
