Porto Alegre
On our return from Buenos Aires we stopped off in Porto Alegre to attend the launch ceremony of a book to which John has contributed a chapter. The title of the book is 'Pensamento Sistemico' - systems thinking.

We were only in Porto Alegre for one night but it was another rich experience - not least because it is the first time I have sat down for a meal in a restaurant at 11.30 at night! More of this in later 'postcards'.
