The fourth intercontinental NHS trip in as many years - another amazing excursion is search of all things natural historical. Black Rhino (and the rest of the Big Five), Pel's Fishing Owl, Puff Adders, armed robbery, tornadoes, lost luggage, serial dysentery and a new species of bird for Namibia! And great fun too, especially with our Rockjumper guide, our good friend Rainer Summers.
