Not sure I want to read it; probably horridly depressing.
Years ago I read Cry of the Kalahari by Mark and Delia Owens Amazon.com: Cry of the Kalahari (9780395647806): Mark James Owens, Cordelia Dykes Owens: Books
Fascinating book, and there was a big section about the great migration.
Those two were nuts! They headed off into the middle of nowhere with absolutely no clue what they were doing; it's amazing they survived.
