Found a couple of spots with > 2000km to go to the sea with EC levels > 900 Yass River upstream Burrinjuck Dam http://osm.org/go/uNaxPLa-- Jugiong Creek at Jugiong http://osm.org/go/uNY%40w7m- Just as well you were only kidding, because this method isn't going to work worldwide. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
