When Sam Powers travels, he buys a one-way ticket. He prefers it that way - as he searches for “Goat man” in Guatemala or participates in Buenos Aires’s annual pillow fight or motorbikes through Vietnam’s Ha Long Bay, he wants the people he meets, not a return ticket, to determine his schedule.

Rebecca Greene knew one thing when she came to college from Elliott County in eastern Kentucky. She was going to leave her tiny hometown of Sandy Hook and become an astrophysicist. No doubt about it.
