For the last of their new adventures, Maureen has arranged a trip the spectacular Brecon Beacons. But it’s not the usual walks amid epic mountain scenery on the agenda. In a first for both, the childhood sweethearts enlist in tank school. After donning cam cream and military gear, the couple get a lesson in controlling a full-sized tank. Maureen’s keen to see if the new vehicle can pick up speed. Their accommodation is another new experience – a shepherd’s hut complete with lush rolling hills for a view and sheep for neighbours. Gareth is a keen clay pigeon shooter and wants Maureen to try her hand at the sport. After getting some tips from farmer and Welsh champion clay shooter, Rhys Lewis, the competitive pair are both determined not to be the one to miss. Meanwhile, Gareth and Maureen’s inability to take one in-focus photograph of their adventures continues. Photographer Rhian Mai meets them at a spectacular natural cave to help hone their skills. The weekend ends where the original adventure began – on one of Wales’ most beautiful canals. Hopes start high as, with a little help, they manage to stay on course and not crash. But it isn’t long before the barge runs aground and the battle resumes to determine who was responsible.
