My friends and 1980s neighbors Lito and John went to Argentina every year, usually in the Fall. (Lito was born there.) I kept telling them that if they would only go a little earlier, before my teaching duties began, I would join them. In 1987, I made it.
We visited Buenos Aires, Iguazu Falls, and Bariloche, then back to Buenos Aires. I returned home from there, while Lito and John stayed another week or so.
Lito arranged all the flights and accommodations. While in Buenos Aires, we also had dinner with different relatives of his almost every night, including one side trip to La Plata. I had a wonderful time.
