I agree the rule is the rule. I agree that shelter is important. And yes, I do carry trash bags with me. <br><br>I think that most of the people on the forum agree with you that shelter is important. Many of us have made studies of building field expedient shelters from found and natural materials. Carrying materials to make shelters makes it easier. <br><br>A lawn size trash bag would take up all or most of an altoids tin. Stuffing a trashbag in pocket along with your altoids tin would add another layer to your preparation.<br><br>I put my lawn trash bag in a sandwhich size ziplock. It keeps the trash bag from unfolding and making a large mess. Since I have kids, I keep one kitchen sized and one lawn size in the same ziplock. I keep a couple of these in the front pockets of my daypacks so they are easy to find in the event of a downpour. They can be made into ponchos by punching a head sized hole in the bottom.<br><br>In my fanny pack and daypack kits, I also carry space blanket bags. They are larger than trash bags, offer the reflective qualities of a space blanket, and are easier to be seen than a black, green, or brown trash bag by rescuers.<br><br>I don't think anyone disagrees with you about the need for shelter. The issue is more of finding a portable shelter that will fit in a pocket sized kit and still leave room for other supplies as well.
