A team of four adventurers departed Wednesday morning from the Marina Hemingway in Havana and are navigating the Florida Straits on their way to Key West . Chris Brinlee, Jr., an adventure photographer, is from Lyon, Colorado. Andy Cochrane, Oru Kayak’s director of marketing, is from San Francisco, California. Wyatt Roscoe, an industrial designer for Quest Renewables, lives in Atlanta. The only member of the team who is not from the United States is Wes Siler, a contributing editor at Outside magazine, who is from London. The four of them are using foldable Oru kayaks made out of corrugated plastic. “There will be no sleeping, no real rest,” Brinlee said.
