I totally get how cold it was. It's difficult for me to comprehend that she didn't turn right around and come back given the conditions. The poor thing must have been desperate to get away, or try to get home, or something.
I get the snow too. Still, it's difficult to understand how she wasn't found that first day. After that, with all the snow, I can see it. I'm sure once they were called and got there, the police and volunteers have done everything they can. I chalk it up to my own lack of imagination that I'm having trouble with this part.
