As far as weather concerns, the OEMC has successfully evacuated the festival in the past.

“We did it once in 2012 and once last year.”

Underground garages, such as Grant Park Underground, the Millennium Garages and the Lakeshore East Garage have been used in previous years as shelters, as well as restaurants and other buildings along Michigan Avenue.

Guidice says that if you see something, you should say something.

“Don’t assume. It may be innocent enough, but we will let law enforcement determine if it’s safe or not.”

The festival earned over 63.2 billion media impressions at a value of over $37 Million dollars.
