Each week Mairead chats to someone all about the obsession in their lives, and this week it's the turn of Mary Harkin who absolutely adores fishing.
Fishing is in Mary's blood - her dad, grandad and great-grandad were all big fishers so it made sense that she followed in their footsteps.
Mary told Mairead what it is about the sport that she loves, as well as her biggest catches and how anyone interested can get started.
