In November 2012, James Campbell and Rachel Goldfarb quit their jobs, left their home in Encinitas, California, gave away most of their possessions, and moved into a 1976 bright orange Volkswagen bus that they named Sunshine.
For the past three years, the couple has traveled, worked, and lived as nomads, logging everything on Instagram (@idletheorybus).
They wrote a book that chronicles their stories from the road to help fund their travels around the US. Called "Orange is Optimism," it's available for pre-order now with expected delivery in fall 2016.
