Lean-to Shelter

This is a lean-to I made while out camping the other day.  It took me about 20 minutes to gather all the materials and another 10 minutes or so to construct it.  If I would have been spending the night in this lean-to I would have kept adding materials throughout the day and continued to make the insulation better.  It is also a good idea to enclose the end where your feet are to keep the wind out.  Another good idea is to clear an area around the opening of the shelter so you can lite a small fire if you get too cold.
