Federico Urquiola (2nd R), 27, a worker in a construction business who is traveling by bus from Caracas to Peru, exchanges money in Cucuta, Colombia, November 8, 2017. Federico said he struggled to get contracts for his construction business and was often paid late for work, when the money had already depreciated. He hoped his wife could join him in Peru. After crossing into Colombia the first thing the travelers had to do was to change their Venezuelan bolivar notes - Cucuta was the last point on the road where they would be accepted. The exchange operations were quite informal and very fast: a cash counting machine and a calculator on a desk. The tension among the travelers was evident - they wanted the best rate possible, but didn't have many options. REUTERS/Carlos Garcia Rawlins SEARCH "RAWLINS BUS" FOR THIS STORY.
