...back in '74, I hitchhiked to Vermont in December but arrived near Putney too late at night to make it to my friend's house. The traffic had ceased, and I was tired and getting cold walking in the winter night.
I had my jacket, wool cap, Sorels and gloves and perhaps too little common sense. There was a good layer of snow on the ground. I found an area off of Rt. 5, sheltered from the wind, to spend the night. I made a depression in the snow a couple feet deep, lined it with pine boughs, gathered a whole bunch more for a blanket and crawled in. I can not say how cold it got that night, clearly well below freezing, but I did fine. The Sorels keep my feet warm, and the pine boughs did the rest.
I do not recall thinking that I could be in deep trouble, it just seemed the reasonable thing to do.
Ah, the audacity of youth.
