Dave Rodney, simply known as California Dave or Sherpa Dave - despite the fact that he's from Canmore in Canada - joins me for this bonus interview on Big Fish. He's one of Canada's most accomplished climbers - and the only Canadian to summit Everest twice - he's a politician, businessman and philanthropist, but most importantly, he was my brother Michael’s climbing partner on his Everest expedition in 1999. Dave was one of the last people to see Mike alive. Their dream was to reach the summit together, but unfortunately fate had other plans. Dave takes me back to the day they reached the top of the world - and Mike became the youngest Briton to reach the summit - and what happened when he realised my brother had not come back down.
