Serengeti. Of all the cats, I think that the cheetahs are the hardest to see. They are solitary. I saw one in the Ngorongora crater. It was a mere black dot in a field. All we could see was the dot of its head poking up from the grass. Twenty or more Land Cruisers were gathered and dust clouds signaled more were on their way having been summoned by radio. I think that everyone was probably disappointed. But, here! We were close up! Our guide drove right up to the small hill of grass and stopped. This cheetah, no name here, just sat and posed. He never moved off even after we left. I feel very fortunate that we saw the major big cats. No, no tigers are on the Serengeti.
