‘On day five of paddling, on the River Gambia, in Senegal, a bull hippo sprung from beneath the surface, about 6 metres in front of our canoes. As we careened towards him, he submerged again. Once we calmed down (after scrambling to the safety of nearby rocks) and grew quiet, our Gambian expedition teammates, Abdou and Ebou, almost in tandem, said, “Wow, that was amazing, it’s the first hippo we have ever seen!” (this is after, whilst on pre- expedition planning skype calls, they had convinced us that “‘Hippos? No problem’)!’ River Gambia Expedition – 1044km source-sea African odyssey
