Synonymous with hospitality, the Berbers invite Barry to take a peek into their lives on a typical Berber family farm. It's been run by the same family for five generations, and it rains only three times a year. And what can you make of a tree full of goats? Only highly prized multi-purpose oil, that's so good for you, international pharmaceutical companies are on a frantic quest to discover its useful properties. It's where olive oil is legal tender for a man and his mule, when they walk around in circles for two months of the year. And a country market with a parking lot for donkeys.
