Bad News: Couple follows GPS directions, gets lost.
Worse News: In the snow on a Forest Service road.
Worst News: They get stuck in 6" of snow in a 4WD. (So how crappy are your driving skills?)
Good News: They are prepared with blankets, warm clothes, food and water.
Better News: They were smart enough to stay with the vehicle.
Best News: Somehow, they get cell phone service and are rescued.
The Good News wins. Lessons learned: Prepare properly for winter travel, know your limitations and for Pete's sake, apply a little sanity checking to the damn GPS instructions.
(Edit, 12/30/2009 2032: A new article says that A) It isn't the Air Force's fault (What numbnuts thinks it is?) and that our intrepid autoists got stuck in 18" of snow; so I'll cut them some slack on the driving skills thing.)
