Coming off last month’s 15th anniversary bike ride, it is again the last Friday of this month and time again for Critical Mass Chicago.

With cooler, and perhaps wetter weather on Friday, turnout will most likely be depressed–a good thing for drivers who will routinely be delayed 10-20 minutes by the hundreds if not sometimes, thousands of riders who have been known to participate in this monthly display of bike power.

Critical Mass steps off from Daley Center Friday evening at 5:30 PM.

Happy Friday?
