This isn't your typical tourist blindly following the gps story. They didn't get stuck until after they'd turned around and were trying to get out:
On other threads, others have said that this guy is a complete idiot. I disagree. He realized he was in deep shit and tried to get out before he got stuck. Not just barreling through blindly like the other tourist/gps stories.
For those that don't care to take the time: Rented car/gps, Lone Pine to Racetrack...in June. Decide to take Saline Valley/Lippincott-the shorter route. Numerous close calls, then car stuck, walk out, finally get cell reception to get a lift. Expensive tow, but free t-shirt. More expensive rental bill and insurance lesson.
