We cluster in order to accumulate numbers. The FCAA is comprised of nine affinity groups. Inasmuch as we can, we will travel as a bloc tomorrow. With 100 people, we can shut down intersections, and will be much harder to arrest. However, given the level of chaos intrinsic to mass direct action, we also devise a tactical scheme to stay in touch should we need to split into affinity groups. We go out into the street to practice street tactics.
