Trip-of-a-lifetime experience arranged by Betchart Expeditions (Cupertino, CA, USA) to celebrate a couple's 50th wedding anniversary. Seven adults and two teenagers spent 11 days of December 2013 in northern Tanzania visiting Arusha National Park, Tarangire National Park, a traditional Masai village, Ngorongoro Crater, Olduvai Gorge, Serengeti National Park, and Lake Manyara National Park (in that order). Trip highlights include a leopard hunting monkeys during the daytime, several up-close encounters with lions (including playful cubs, feeding on a buffalo kill, and two mating pairs), and thousands of migrating wildebeests. www.betchartexpeditions.com
