Given the scenario, I would have walked out too, without hesitation. To do otherwise would have been silly, and would have worried family unnecessarily.

The only big (REALLY BIG) question would be whether to stay with the road or go cross-country. Intimate local knowledge and maps would be the tipping point in this decision. Without those, I would have stayed with the road. Yeah, logging and oilfield roads meander all the heck over the place, which is annoying. But on the road you won't get turned around, won't sprain an ankle, and you are moving closer to rescuers, who will probably check the road first anyway. You can also keep moving after dark, though very cautiously if it's bear country.

IMO they did everything right. They took charge of the situation, assessed things carefully, took responsibility and got down to business. Pretty much a yawn, survival-wise.

Tell the nervous nellies at work to buzz off and watch more TV.
