I'm sure this probably wont apply for most on this board, but just in case anyone is still not aware of critical mass: This is a really fun event to promote awareness of bicycle culture and the importance of sharing the roads. The ride happens the last Friday of every month. Here is a link to the Chicago ride site: http://chicagocriticalmass.org/.
I am interested in everyone's agenda in riding. I know some riders out there (like me) are in it for the fun and camaraderie of it all...anyone do it for another reason?
