Many times; a few examples follow.....have any of you ever planned a trip to a zoo or aquarium to see a specific species you've always had a strong desire to see?
I went to Paris in 1987 specifically to see my first aye-ayes and returned the following year to see my first sifakas.
I visited Liberec Zoo, when it had the only golden takin in Europe, especially to see this sub-species for the first time.
Closer to home, I visited Brighton Aquarium especially to see my first marine sunfish.
