I've never been to Chessington being put off because of the very reason of it being in a theme park which I've got no interest in. I do find it a cultureally and historically interesting zoo though. What is Trail of the Kings? I know there's been the debate of the gorilla enclosure. Hoiw much is that similar to the Howletts inspired Chimp and Gorilla enclosures of 1984? Finally when did Chessington stop keeping Chimps?
