Pole Markers:  As a reminder, location identifiers signage or “pole markers” are posted along the Lakefront, DuSable Lake Shore Drive, and Grant Park. “Pole Markers” serve as visual aids for the purposes of location identification by an individual and/or a first responder. Whether lost, Injured, or witness criminal or suspicious activity, anyone can look up and call 9-1-1 and give the letter-number combinations on the pole nearest to your location to help first responders locate you as quickly as possible. You can also use the identifiers to let friends and family know where you are if you become separated while you’re enjoying one of Chicago’s events. 

Report Suspicious Activity:  If You See Something Say Something. OEMC reminds the public to be aware of their surroundings and to report suspicious activity. If you notice something suspicious, notify onsite security or call 9-1-1. If You See Something, Say Something™ is a national anti-terrorism public awareness campaign that emphasizes the importance of reporting suspicious activity to law enforcement authorities.
