Certainly no disgreement here. Some means of shelter should be carried by anyone going afield. People like me are likely to have a trash bag even in town not to mention what my attache contains (more toys that work!). That being said, the most important shelter ingredients are a head for finding shelter in the environs and a knife. Add to that some paracord and perhaps some duct tape, and "things" are looking much better even without a carried barrier!
