Kathy and Craig are dedicated to each other, and to hiking, in that order. Their second date was a 20-mi (32-km)dayhike in Arizona. Since then they haven't stopped for long.

They've trekked through much of the world's vertical topography, including the Nepalese Himalaya, Patagonian Andes, Spanish Pyrenees, Swiss Alps, Scottish Highlands, Italian Dolomites, and New Zealand Alps. In North America, they've explored the B.C. Coast, Selkirk and Purcell ranges, Montana's Beartooth Wilderness, Wyoming's Grand Tetons, the Colorado Rockies, and the California Sierra.
