Your hosts are long-time Alaskans, Roger & Arlene Cowles. These two are some of the most adventurous people you'll probably ever meet in your lifetime. They met in a most unusual place... Utqiagvik, AK formally known as Barrow.
Roger Cowles, rode a bicycle he custom built, 1,160 miles from Anchorage to Nome, on the Iditarod Trail. This was the first time that any modern day cyclist had ever rode this winter trail of snow and ice.

Arlene Cowles, spent 7 summers kayak touring around the coastal waters of the Beaufort Sea, the Chukchi Sea, and below the Bering Strait, the Bering Sea. Plus, a bit in the Gulf of Alaska. In 1989 her and previous husband, Martin Leonard III, kayaked from Nome to Wales and then cross the Bering Strait to the village of Uelen, then continued southwest along the Siberian coastline ending in Provideniya. They left their kayaks in good hands at the dock and then flew with Bering Air to Provideniya's sister city, Nome, AK.
