A woman who had been trapped in her car by the snow storm was rescued by the Maryland National Guard late Monday. No details on what happened, but this occurred in a suburban part of Maryland just outside of D.C. TV report here: http://wjla.com/news/local/woman-stranded-in-car-since-friday-in-maryland-rescued

First thought take away for me is to keep car emergency supplies in your car at all times. Though there are few details in the story, it seems she wasn't that far from help, yet still ended up in the car for 3 days.
