Travelers should not rely solely on technology such as GPS for navigation, after a Canadian couple lost in the Nevada wilderness for 48 days. Albert Chretien, 59, and his wife Rita Chretien, 56, sought a shorter route between Boise, Idaho and Jackpot, Nevada during a road trip from British Columbia to Las Vegas. Rita Chretien drank water from a stream and rationed meager supplies until hunters found her on Friday. Albert Chretien has been missing since March 22, when he went to seek help. The Chretians mapped the route on their hand-held GPS, an electronic device tied to global satellites and commonly used for navigation. There are times when you need to put the GPS down and look out the window, said Howard Paul, veteran search and rescue official with the Colorado Search and Rescue Board, the volunteer organization that coordinates that states missions.
