Critical Mass

In the nearly ten years that Critical Mass has had a presence in Chicago, hundreds upon hundreds of area cycling enthusiasts have shown us a glimpse of the world they envision: one where cars aren't the main source of transportation on the landscape. A self-described "visual demonstration," CM's monthly rides - held on the last Friday of the month - are considered to be a sign of the strength of the city's biking community.

Don Sorsa caught a series of bikers during CM's most recent ride and this one was Chicagoist's favorite.

Remember to tag your photos with "Chicagoist" in your Flickr streams to be featured next week!
