Recommendation: For anybody considering going to rallies or marches, rather than rely on your flimsy flag poles or sign poles, use bamboo. Bamboo is almost unbreakable and delivers a wicked blow. In so many videos I see patriots using store bought flag poles and they snap or get broken with the first hit. With bamboo you can pass through security checks for weapons (make sure there's some sort of banner or flag tied to it). When the shit hits the fan, you are prepared. Five to six feet is the optimum length.
