2 years ago I went backpacking with a group of friends in the early winter, it was snowy and a good amount of snow was on the ground,, so instead of a tent, we set to on a bad ass shelter. We leaned a bunch of llimbs against a tree, teepee style, lined the outside with pine bows and another layer of sticks, lined the floor with pinebows, a space blanket, and more pine bows, and crammed 3 people in it. It was so warm we woke up in the morning with melted chocolate in the shelter.
