Catriona picking up something shiny from the sewer grill in an alley by our house in downtown Hsinchu. She turned out ok so I guess she fought off whatever toxins she might picked up from that and a multitude of other things she picked up from the roads of various Asian cities. The Taiwanese are experts at constructing drainage but often residents would circumvent city engineers efforts by covering drainage grills with rubber mats. The rubber mats stopped the deluge of large cockroaches which would stream out before earthquakes or during intense rain.
