The A-Frame shelter is one of the most basic shelters out there. Instructions on how to build one can be found in almost any book on bushcraft or survival manual, so I'm not going to give instructions on how to build one. I will say that although it is easy to construct it's also time consuming. It took me about two hours to build the one shown in the pictures, but the outcome was well worth the effort. Experience has taught me that giving your shelter a little more attention gives you a much better nights sleep.
