The Great Migration/River Crossings

The main ingredient in the "great migration" is several million wildebeest. This is basically a trek by large herds of animals seeking out the best grass to eat, from the southern Serengeti, up to Masai Mara. A highlight in the migration is the river crossings, especially the Mara River! They can smell the rain and better grass to the north, so they MUST risk all the dangers, and cross this river.
