18-year-old Tran grew up in California, but was born in Vietnam. Her father, who is retired, decided to move back to Vietnam two years ago. When Tran graduated from high school last year, she decided to join him for a year before starting school.
"I spontaneously decided to take a gap year because I wanted to see some of the world before I saw another Scantron," Tran told The Huffington Post. "And it just so happened that my dad was in a place I've always wanted to get to know better."
Tran and her dad have been traveling around Vietnam on their mopeds for the last five months. On May 11, they were on a hike in the mountains near the city of Da Lat when Tran noticed her dad doing something a little odd.
