On the final day of our trek from Edmonton to Calgary to raise money for clean water overseas, we're just outside the city limits of Cowtown. I can see Calgary's skyline, and after 10 straight days of walking on my hands, it's like a mirage in the desert.

Never tell Spencer West that he can't do something. A congenital spinal disorder rendered his legs useless, so at age five, West underwent a double amputation to remove them. His biggest challenge -- so far -- was climbing Mount Kilimanjaro for charity last June. Today, we were with West as he kicked off the We Walk 4Water campaign, starting a 300-kilometre trek from Edmonton to Calgary.
