I agree that having a plastic shelter is a great idea to keep available with the PSK. <br><br>I carry a Tacoma Mountain Storm Shelter tube tent in the back of my vest at all times along with some paracord. Because of the bulk it is not actually a part of my PSK but a part of my EDC.<br><br>Looking at mebrad's excellent post (could you survive for 4 weeks on your PSK?), his FIRST DAY would be much easier with a plastic tube tent or larger sheet of plastic. Then as he states subsequent days are used to improve the shelter etc. It is unlikely that a plastic tube tent will last thru a major storm or even the stresses of 4 weeks use, but I think it gets you set up with decent shelter for the first few critical days.
