A cautionary tale for those of you traveling in wintry weather

"A Reno, Nevada couple got stranded in wintry conditions for three days in the high desert of Eastern Oregon when their SUV's GPS gave them misguided directions and took them down a wrong path. Ask me and I'll tell you that the only wrong path they took was trusting their GPS.
The Klamath County Sheriff, Tim Evinger, clearly a kinder soul than I, was quoted saying "GPS almost did 'em in and GPS saved 'em." Evinger said. "It will give you options to pick the shortest route. You certainly get the shortest route. But it may not be a safe route." After almost three days, they miraculously recovered a weak cellphone signal on a GPS-enabled phone which sent its coordinates to 911.
Actually what saved them was the fact that the couple, both in their mid-to-late 60s, were prepared for winter travel, carrying food, water and warm clothes. Their four-wheel drive Toyota Sequoia was pulled out of the snow with a winch after they were found by a Lake County deputy in the Winema-Fremont National Forest, outside the town of Silver Lake.
John Rhoads, 65, and his wife, Starry Bush-Rhoads, 67, made it home safely to Reno, Nev., Evinger said. "Their statement was, being prepared saved their life," he said."
