We saw a lion at Tarangire. It was 200 meters away in the riverbed. We called the other truck and watched the lion through binoculars for half an hour. It was the highlight of the trip up to that point - a glimpse of a lion.
The next day, we drive into Ngorongoro and 45 minutes in, we drive right by this lioness napping on the side of the road. We entered a different world.
