Ah the Police Treat....that takes me back!
I remember being able to watch the rock being made in a shop in Castle Street...was it called Gores???
I also used to love going into Blacks(??) the pet shop on Victoria Street next to Gellings Foundry which I think is somewhere near where MT building is now, they used to have cages full of kittens and puppies and a parrot that shouted at you!
I remember there were loads of amusement arcades throughout the main shopping area and a cafe called the Golden Egg(??), I also was taken, as a birthday treat, to the Mayflower chinese in Castle Street, it was sooo exotic!!
