This idea has been floating around our local Critical Mass e-mail list lately, and it's a cool one. If you're visiting another city and want to try it there, check out this worldwide Critical Mass list and see if that city has a Mass. Bring or rent a bike and go for a ride!
If you live near here and want to explore the city in a different way, get on your bike and join in tonight's Critical Mass ride. It meets at 5:30 at Daley Plaza and leaves the plaza for points unknown around 6:00. It's a party on bikes, an urban adventure and a helluva fun ride.
I heard that a crew from the Travel Channel will be filming tonight's Critical Mass. How cool is that?
