Have just uploaded some scans of slides that I took at Auckland Zoo in 1990 when I attended the ASZK conference (no pics of the conference though).
Going through the more recent photos I noticed some comparisons I found interesting - 20 years on, some things look like very little has changed, except the grass in the giraffe enclosure.
