Off we went, accompanied by Keenan and an armed guard. The idea is to avoid getting dangerously close to any big game, but the guard is there as a precaution just in case. Walking safaris are great for spotting the small things you wouldn't notice from the car. We saw elephant prints, a hippo skull, the strange fruit of the sausage tree and jackal poo - white from all the calcium in the bones they eat - amongst other things.
It was a great, really atmospheric experience. You get a much better feel of the scale and realise just how vast and wild the bush is.
