I was just thinking about it, I usually smoke at home, and I usually smoke flakes, which need rubbing out. This makes it hard to, I dunno, bring your pipe to a barbecue at a friends house. Especially if your planning on smoking outside. Fill your pipe, at home, and either wrap it in tin foil, seran wrap, or, the best, just pop a wind cap on it and take it, when your ready to smoke, just light it up
