Alarm set for 5:30 to be up for an 8:00 am flight from the BA domestic airport to Posadas which is the city and airport closest to the marshes and wetlands in Iberà where we're going to spend the next three nights.Hugh arrived with his driver at 6:30 to pick us up and drive us to the airport and just as he did the skies opened up with torrential rains so we raced to the car through an overflowing stream that had already overrun the gutter. Given the weather, happy to be leaving....
