n 2000, Herman and Candelaria Zapp set out on a 16-month trip from their home in Argentina to backpack around Alaska. But that trip has turned into a round-the-world saga spanning 15 years that would leave the most hardened vagabond green with envy. The couple left their comfortable life in Buenos Aires behind, and became adventurers extraordinaire. And their mode of transportation has been as unconventional as their lifestyle is enviable—a 1928 Graham-Paige Model 610. The 87-year-old vintage car, with a top speed of 35 miles per hour, looks like it came straight out of a 1930s Hollywood gangster movie, and it doubles as a home for Herman, Candelaria, and their four children.
