Richtersveld, South Africa: This is one of the hottest places I have been. But the plants are very interesting and you have the Orange River to cool off. Watch the monkey's because they are watching you!
This enormous nest near Aus, Namibia, is actually a bird apartment complex. The Social Weaver birds found in Namibia and South Africa live in community nests. I don't know whether each bird has its own apartment number and mailbox, but evidently they have no trouble finding their own dwellings.
