Dianne Roberson of Yass New South Whales, Australia, arrives Friday in Durango with the Black Dog Ride. The ride began in 2009 as one Australian man’s motorcycle journey to raise awareness about depression and money for the group Suicide Call Back Services. Today, the ride has developed into a national Australian suicide-prevention charity. This year, over 21 days and 4,000 miles, the Black Dog Ride will share its mission with America.
