I took a night bus from Resistencia to Salta (there were no busses doing the trip by day). It was raining most of the night, and when I came to Salta it was wholly grey, and drizzle for the entire day I came there. That did not look promising, as I had come to see all the views around Salta. But by evening the rain ceased, and the sun appeared, and it would not rain for the next twelve days I was in the area.
