This is the Parana River. It is similar in size to the mighty Mississippi River.

The tree line you can see on the far side is Paraguay.

There were myriads of stands, like flea market stands, on one of the main streets near the river.

We were told that the items they sell are quite cheap compared to buying the same thing in Corrientes

becasue vendors cross the river from Paraguay and sell their products without having to add on the 20.1% tax.
