The 24hr of Tremblant is a charity ski marathon that raises millions of dollars for children's cancer charities every year. It's a genuinely touching, heart-warming event. But it only lasts 24 hours. This year, The Wishwagen changed that. What started as an on-site activation and microsite grew into a movement, as more and more people around the country sent good wishes - and sometimes very personal stories - to help lift the spirits of these courageous children.
