Chilling in the Park
Not much to say about this one. That's the Prudential Building. If you doubt me, read the sign at the top. It was completed in 1955--the first skyscraper built in Chicago following the Great Depression. I am standing in Millennium Park's Lurie Garden. There is still a surprising amount of wild grass and plantings in the garden's beds.
No tricks on this one. That's what the sky looked like. I appreciated the red lighting on the second Prudential tower immediately behind the 41-story original one.
