742 Sharks; Beyond Havana; Pompeii

A deep-sea diving instructor from Australia explains why he's not afraid of sharks — well, most of them. Then a Cuba travel expert looks at the places and experiences you can explore beyond Havana, as well the rules that govern travel to Cuba for US travelers. And a guide from Italy helps us step into a day in the first century, frozen in time, at the ruins of Pompeii on the slope of Mount Vesuvius.
