I'M HOPING there's an avid Weston historian out there who can help me settle a long-running bet between my wife and I as I've been unable to find an answer on the internet. Does anyone know when the last paying customer was accepted at Knightstone swimming baths, and also the first at Hutton Moor leisure centre? I'm saying we taught our children to swim at Hutton Moor as Knightstone had closed by then and my wife says the opposite. Our son was born on December 13, 1981 and I'm hoping that someone will say that Knightstone closed before then, as there is a substantial wager on the outcome!BARRY TOMKINS - Cromer Road, Weston
