The attached photo has details of the angling club on the pond adjacent to the hall (separate from BGCA), with a membership form and details of the officers. It's also on display in the external noticeboard of the hall. Surrey Hills Cafe has day tickets for sale and membership forms. They have a new website with all their contact details on : https://bearegreenanglingclub.co.uk/
(BGCA doesn't have any more info than that - the trustees and hall bookings secretary aren't anglers, so please don't ask us any questions, we won't know....use the contact details for the angling club on their website or on the attached photo).
