Bearded Martin, wearing a red helmet, smiling as he pokes his head up through a opening in an overgrown man made hole in the ground.

With much sadness, we announce the death of Martin Dixon on 15/10/2025, having had cancer for over 5 years. He was a long-time member, former chairman.
He & Linda enjoyed many happy times together, including organising numerous Sub Brit trips.
We'd love to hear your anecdotes & memories of Martin.
