Hi folks, critical mass was a great success this year. It was amazing fun! We went over almost every bridge attached to downtown, which wasÂ very satisfying.Â I felt like I was in a swarm during the ride. It is quite fascinating how the swarm moves. Sometimes individualsÂ from the swarm stop at the intersections and in various necessary places along the way. Other members of the swarm thank those individuals for stopping. This stopping is called: blocking or corking. As the swarm moves, the stopped membersÂ are swept back up by the moving mass.
