The northern Spain sun beat down on Deb Schmidt as she guzzled water and followed her husband, Don, to a roadside café. They lunched there before walking several more hours that day on the Camino de Santiago, a six-week, 500-mile walking pilgrimage. She was grateful to rest her sore knees. On the first day of their route, which began Sept. 1, 2013, in St. Jean Pie de Port, France, the mountainous climb had caused the injury to set in. But it was not enough to deter her from completing the pilgrimage, which wound westward to Cathedral Santiago de Compostela. God willing, they hoped to reach their destination by mid-October.
