Tonight's critical mass

we've been
warned

Yesterday, Chicago's Finest uploaded a Chicago Alternative Policing Strategy Bulletin to the Worlwide Critical Mass flier exchange:

In order to ensure the safety of residents and visitors to the City of Chicago, all ordinances will be strictly enforced, including the following: List includes rights and duties, headlamps and reflectors, riding on sidewalks, no corking, disorderly conduct, public drinking, and penalty amounts.

At least it seems
we don't have to
wear helmets.
