A pleasing match-up, this. I've been to Zagreb but not Bristol. They are both small urban zoos, and whilst Bristol is well-renowned for doing a lot with a little, Zagreb doesn't get the attention it deserves for achieving the same thing. This is going to be interesting. The concept behind this poll is explained here: ZooChat Cup In summary, the rules of the game are as follows: - You may choose whatever criteria you like to decide how to vote, as long as it only relates to the category of 'primates'. - You can use whatever resources you like to inform your vote, including Zoolex, Zootierliste, the ZooChat gallery, trip reviews, zoo maps, books and wherever else. You don't have to have visited both zoos to vote. - Votes are public and can be changed at any time before the poll closes. - The aim of the game is to provoke debate. Post explaining why you voted the way you did, and why others should join you. - The one thing you can't do is vote based on anything other than primates. - Voting closes in seven days.
