A couple was rescued by a snow plow driver after their car was stranded for 12 days in deep snow.

this is interesting winter survival story. The couple cut up their car seat foam to use as snow shoes. They were wearing only basic jeans & shirt & jacket. Jeans is really a poor choice of fabric for the winter.
