There's nothing quite like the thrill of the first leopard sighting. Nocturnal, secretive and with a distaste for humans, leopards are the megatick encounter in Kruger. Mine was a big male snoozing on an outstretched limb of a large leadwood on the S28 just near Nhlambanyathi Hide. It was picture perfect but seemed disinclined to move. I watched and waited. Other drivers got bored and left. Then sky behind it darkened and the first spatters of rain hit the windscreen. The leopard sat up, clearly irritated, its ears flat. Then it picked its way along the branch and leapt down the tree. I just kept my camera shutter clicking.
