It's Critical Mass.
It was a little nippy out there today, but still a good turnout(60+), I thought, for a March Critical Mass ride. One guy did get taken down right in front of me, when one of the peddle cops decided to stop and shove his bike into they guy when he strayed over the yellow line. Seemed kind of excessive. Like the cop just snapped and decided somebody's going down. But for the most part things seem to be pretty good with the police. They send some bike cops along with us and have a few squad cars in the back. We ride around the city yelling "Happy Friday!".
