Smoke

As we went to go to the gym yesterday evening after work/school, we walked out of our building and into a noxious haze.  We though that something nearby was on fire, but we really couldn't figure out what it was.  The haze was still there an hour later as we walked home, and we were reluctant to go back out again.  Finally, we got the story from one of the teachers in Kat's program when we joined a group at a tango show.  Apparently farmers in the Delta in the Parana river have been burning brush to clear their fields, and all of the smoke was blown into Buenos Aires.  It was nasty.
