Make sure to mark your calendar: the Sun-Times reports that Allstate Insurance is paying to close off portions of Millennium Park for a private shindig on Monday, August 7. The Crown Fountain will remain open to the public, and The Bean will remain open to the public until 4pm. In exchange for getting to rent out the public park, Allstate is also kicking in $500,000 for some free concerts at the park this summer, which will include the Gospel Music Festival and a performance by cellist Yo-Yo Ma.
