Yea, guess your right. Practicing primitive skills is useless. Cause when your all cuddled up sleeping like a baby in your ponchos and these enemies you speak of wake you up at gun point, probably with a suppressed gun and a can of crisco, just tell them to give you a few minutes to pack up your shelter before you run for your life. That way you can set it up again if you get away cause you are going to die with out it since you haven't been practicing your primitive shelter building skills.
Good luck with all that.
I will just learn as many skills as I can so I can survive even if I happen to lose everything on me. Including my ponchos and space blanket and para cord and zippo lighter and my whistle with the matches inside and the compass on it and my knock of Rambo knife with the welded on hollow handle holding my fishing kit and my bear grills ultimate survival knife I keep as a back for when my Rambo knife fails on me and it will.
