Went to the unusual town of Tigre today.

Went to an area called The Delta today, town of Tigre built on a myriad of islands formed by the river delta.  No roads... only rivers, streams and canals.  When you think of 'car', think boat.  Kids go to school on the schoolbus boat, garbage collection boats, super market boats that go from island to island, etc.  We saw the slums and the wealthy section, with mansions and helicopters to go to work in Buenos Airies! It was a great day whizzing through all of this on a Zodiac!
