Ro writes to say, “This is a photo of me preparing to descend on a zip-wire in the Copper Canyon in Mexico – I travelled in northern Mexico last year with my son Tom, and we descended into the Copper Canyon on a series of seven zip-wires which was simultaneously very scary and totally exhilarating. Over a three week period we went up the Pacific coast then through the Sierra Madre to Chihuahua, by car, bus and the only passenger train in Mexico, the Chepe, finally visiting the pre-Columbian pyramids at Teotihuacán near Mexico City.”
