There is never a good place to get a puncture. Deep in the heart of lion country is probably bottom of the list. We are in Kenya’s Masai Mara reserve, spiritual home of the safari, where a golden landscape of savannah and scrubland populated by acacia trees stretches as far as the eye can see. The Mara, for once, is empty of tourists. We have the park to ourselves during a fleeting moment when predators outnumber safari trucks and human traffic is at an all time low.
