I have a vague recollection of visiting the shark enclosure at Sydney Taronga Zoo when I was a small child. It's since been replaced by a modern glass tank but back then it was just a very large pool inside a building. Visitors would walk out over the pool across a timber floor, to look over the edge at the sharks below. Alas, if you looked down between the wooden boards, there were glimpses of the water underneath. I think my Dad might have made a joke that if the timber gave way, I'd fall into the shark pool. That was it for me. No way I was going in there. I suspect I may have had a tantrum and flatly refused to go inside. Years later I still had a distinct dislike for walking along the piers at Redcliffe and Sandgate, where the timber is placed wide apart and you can see the water below. What brought back this memory? Walking over a cattle grate!
