No but I'm very familiar with the space. With no offence meant, I think your memory is massively over-estimating the size of those islands. Even joined together they are not really that big. I remember always feeling one was a bit small for the siamangs. But in any event, what would be required to turn it into an orang-utan exhibit would be so extensive that it would negate any advantage of the existing islands being there. I look forward to seeing what Auckland do. But with those structures they have designed/built so far I'm not holding out for anything not artificial.
