Welcome to the Luangwa Valley, Zambia. With a spring in their step and excitement in the air, Luca and Melua clamber on up into their safari vehicle to set off with their guide on their first game drive in Zambia. Who knows what they'll find. Over hills, through trees - their eyes are peeled for any creatures that may cross their path. Suddenly, in the clearing, some rather tall spotted specimens. It's a whole heard of Thornicroft giraffe and their babies.
