We arrived coming from Flossmoor Rd to the east side of the venue and parked in a lot on the SE side.
First, we were late arrivers (15 min after the opening act was scheduled) due to work and being from the NW burbs. They do a poor job online of explaining what this is, but well worth it.
Took the whole family to a great sold out Imagine Dragons show, so opted for the cheaper lawn seat, but thankfully had upgraded to the preferred lawn.
