Herman and Candelaria Zapp started a 12,000 mile journey in an 83 year old Graham-Paige vehicle given to them by Herman's grandfather. At first their goal was 'just' to travel from Argentina to Alaska, but that journey has stretched into 142,000 miles, and 4 children in the 11 year journey, that isn't over yet. They are home schooling their children, each born with a different nationality. The kindness of strangers and sales of their two books cover their expenses as they've driven the antique vehicle (at a maximum 40 MPH) on 4 continents. They have no plans to stop any time soon as they travel the world.
