Crossing in Iguassu seems to be a work in progress with some glitches today:

Iguazú is right in the Tres Fronteras área, where everyone is desperate to recover the money they used to receive from international tourists, specially Argentina and Brazil. In other political circumstances, a special agreement limited to that area would be a  predictable outcome.

However, Bolsonaro and Kirtchnerism are in confrontation, trying to fuck each other. It is very hard to predict what is going to happen.

My only other observation at this time is that packing in too many destinations can be qualitatively shortchanging, especially if you have future prospects for returning. 

I’m going to spend a month in Brazil.   Right now the tentative plan is two weeks in Rio, one week split between Salvador and Iguazu (thanks for the heads up about drought conditions) and I’ll spend my final week in São Paulo.   But of course this is all subject to change.   I’d love to see the northeast states.  Amazonia of course. The Patanal.  Belo Horizonte, florianopolis, etc.   that’s for next trip.
