Travel around the world length of 11 years
Herman and Candelaria Zapp has been 11 years traveling the world on his 83-year old Graham-Paige car and do not intend to stop.
Initially, they planned to just ride from Argentina to Alaska, but their trip was delayed. During all this time they managed to drive over 142,000 miles and to get 4 children having different nationalities.
Oddly, but kindness counter people, as well as royalties from the sale of two books, with more than enough to cover all costs associated with travel.
