Geography is not my strong point, but our Birmingham friend, Paul, had been in touch and I spent a while looking at an atlas a few days ago, comparing notes with him on places travelled. This time we weren’t discussing the canals of Birmingham, which are many, but another grand water feature, Foz d’Iguaçu. He had recently returned from Argentina, one of the countries from which those falls are visible. Shane and I had seen the same falls, when in Brazil. It was a highlight and, we all agreed, hugely more impressive than Niagara falls.
