died

I was trying to take my 4-wheel drive up the snow-covered mountain to get to my house. When it became clear that I wasn't going to make it in low 4, I got out and winched up to a tree on my property in order to get a boost. (The snow is about 4 inches and fresh) As I'm winching up the grade...
