Happy 3rd of July!...
I spent the evening on the roof of the east tower at Marina City (surprise, surprise), along with hoards of others, which prevented me from capturing any real images of the fireworks themselves. But, here is the reflection of the fireworks in the building to the right of the Hancock.
A view of the hoards on the roof of the west tower watching the show as well.
After the main show was over, the secondary show lay out across the city and the suburbs. For hours you could see illegal fireworks going off as far as the eye could see.
