While taking 'City Scape' images the other night this lively group asked me to take a photo on their camera, so I did a trade with them and took a photo on mine as well... I think they were from South America and they were making the most of their time in Auckland.. 'City of Sails'... The Siren that sounds.. is to warn pedestrians that the bridge is about to split in half and rise up so as to let boats through...
