In your Kits I hope you have some sort of shelter plan. This is an example of a super easy and fast shelter that will get you through the night. Will it be fun, no. Will you live, yes. This poncho lean-to with a space blanket is a quick set up for cold weather with no precipitation, basically a reflector. We had to let the fire burn down a little cause my son got to hot. It was 10 above at the time. If you have never built a shelter in the winter you should try it. It is a lot different that in warm weather. Your shelter material is not near as pliable, you have gloves on, the ground is frozen, and it's cold!!!. If you think you might have to spend the night out in below freezing weather, at least have a plan on shelter, fire, etc... By the way the reason we were out in this weather was to teach about 200 Scouts about emergency shelters. Be Prepared!!
