Critical Mass by Chris Carlsson

I have been reading this book about Critical Mass.  I have participated in it in the past and for me it was for a fun, pro-bikes, festival on wheels traveling through the city.  As I read through this book, there is so much more to mass on top of the rolling party on wheels.  It is an intersting read.

Available on Amazon here.  It also reminds me that I have a lot of reading to do with other biking, commuter, cycling, messenger books..
