Making smart decisions in survival situations is the difference between being another statistic, and coming home to your family. Being prepared is essential every single time you head outdoors. Most people in a surval situation think about building a lean to shelter, the various TV shows are littered with them, but they also show the downsides of them.
Lean to survival shelters can block wind from one direction, but the real disadvantage is that it does very little to protect from swirling winds, wind blow rain – and most importantly it will do nothing to trap in warmth. Even in late spring, the temperatures can frequently drop into the 50’s at night. Add in some wind and cool rain and it can spell disaster for those in a survival situation. In these situations, a wilderness shelter that is fully enclosed on all sides wither either a small opening, or preferrably a door, will trap valuable heat in and keep the wind and rain off you.
