I'm a researcher working in a wide range of Maasai communities over the last three decades. Charles took charge of me and my colleague and ferried us to all sorts of remote parts of Simanjiro plains with great efficacy and good humour, dealing with navigation through remote areas, inevitable traumas of complex logistics, finding unexpectedly comfortable and good value accommodation and eating arrangements, and swiftly and professionally sorting out punctures and everything else we threw at him. oh, and we saw some spectacular wildlife too. Charles and his vehicle were great. Thank you Charles!
