Mass it up.

The Critical Mass bike ride is one of my favorite things to do in the city. For those who aren't savvy to Critical Mass, in just about every major city in the world on the last Friday of the month the bicycle community meets in the town square (in my case Daley Plaza) at 5:30pm and by 6:30pm we all begin to ride around the city for about 3 hours. I began attending this ride when I was new to the city and it was a perfect way to learn the city and meet other bicycle people. The ride has been pretty crappy since Chicago's 10th anniversary of the ride about 2 years ago. However last Friday's ride was stellar. We had well over a thousand people on the ride, great weather, and the police were more agreeable than they have been in recent months. Check it out in your city.
