Thanks to the pioneering work of Michael Leunig it is now a well known fact that shopping trolleys are not made in factories, but have a complex life cycle that traverses the seas, rivers, canals and drains. When it comes to mating season not all trolleys make it all the way back to sea, and occasionally they are forced to lay their eggs in the drains. Today on an expedition to photograph the Chatham Road bridge I spotted this infant trolley emerging from the mud at the bottom of the Styx Creek drain in Hamilton North.
