Back in the late seventies some potholing pals of mine managed to get inside the underground wharfs under Dudley Hill where they found a huge complex of canals, warehouses and all sorts of stuff from WW11. Looking for an exit they worked their way upwards and eventually came out inside the bear enclosure! The keepers were amazed and actually asked them if they would do a survey of the tunnels. Can't imagine 'elf an' safety would allow that nowadays though.
Sadly Dudley as a whole is in need of a bit of TLC. The Merry Hill centre really hit the surrounding towns hard. Likewise Stourbridge is full of charity shops, Cash converters and cheap pubs. There are more empty shops every time i go there.
Dudley zoo is on a great site and could be really good, they just never really got it together there. Agree that Jersey Zoo is among the best, but it was eye-wateringly expensive last time we went there.
I hate the dea of zoos now, though i recognise there is the odd important bit of conservation work going on... it just seems wrong to have animals penned/caged/whatever... watch a wildlife proggy if you want to see what they can really get up to...
A few friends of ours have rabbits too... spend most of their time locked in hutches... it's just wrong imho.
