The first mission is in motion before dawn, in the cold damp hours steaming from blankets and pallets, they head out into the mines, down in the trash of last night, cans, bottles, cardboard, treasure, separating into black plastics for the scrapyard scales. They range slow burdened and sure, investigating and scrutinising, every find is a fragment closer to a piece, a cap, a packet of two rand biscuits.
