Merry Christmas, everyone! Thanks to those who wish me well.
It is true what they say about the waterfalls of Iguazu. They is everyone, in that case. The pictures I have made don't distinguish themselves from the mainstream holiday pictures, but what can I do... go there yourself if you want to see more.
The level of violence in the comments is most entertaining, although nothing else had to be expected on Christmas.
A short note: I don`t consider my return as sign of weakness, or "giving up". I did not come to South America on a mission, and I achieved and experienced more than I had expected. But I am curious, and I have ideas what to do next. You will see.
