I did the grown up thing and caught a taxi from the airport to my accommodation in Buenos Aires. It was worth the extra dollars for the ease and speed after a long haul flight, particularly because my driver, Martín, was so nice. He was happy for me to converse in my very rusty Spanish and pointed out interesting things on the way. We managed quite a chat, and it transpired that he is really a journalist, but since the economic crisis in Argentina (one of many that have plagued the country for most of the last hundred years) has been driving the taxi to and from the airport ad infinitum.
