While I was watering the dying trees on Omaru Creek (please rain soon) I noticed people were putting out their trash for the local in-organic rubbish collection. So I hauled a bunch of stuff out of the water. Some of it was so rusted it must have been in there for years. The pile was bigger but some of the stuff I found in the bush (bike parts) got picked up by some collectors (sweet!).
UPDATE: Inspired by the recyclers my son and I just pulled out about 60kgs of rusting steel from below the high tide line. I would have photographed my pile of fencing mesh, corrugated iron and shopping trollies but they picked it up so fast!
