I’m talking about Kenya’s world-renowned Masai Mara Game Reserve. It’s the best place I know to start my countdown of amazing habitats. And plenty of animals agree with me. Every year in June, millions of wildebeest and zebra arrive from the dry Serengeti plains in Tanzania, searching for sweet grasses and water. To get a new perspective on this spectacular migration, I signed up for a sky safari with balloon pilot Greg Russell.
