Ireland, Lithuania and Croatia. Other locales include 
Burkina Faso, West Africa, and Taiwan.  AOL*The show will crisscross the world, from

*"There are probably four places that the average person is going to hear and say, 'They're going where?' And they're going to have to get out a map to know where it is. They are very remote," said Bertram Van Munster, the other half of the executive producing team. 
"We hit most of the continents, except Antarctica."
