A bit of fun here- If you could travel back in time and visit any zoo (or even your favourite zoo) where would you go and what point in time would you choose? I fondly remember my first visits to the Aspinall parks in the early 1990's (when the collections were unique), so I'd visit at a point where I could see those frustratingly elusive (for me) Sumatran rhinos! I never saw them, and will probably never have another opportunity to see the species. I'd also want to visit London at a time when the collection was at it's peak (50's/60's?) though I'd probably need some help from fellow 'chatters as to exactly what time to pick!
