An Occupy Wall Street offshoot is sponsoring buses to bring protesters to Chicago for the NATO summit.
These protesters plan on surrounding the Boeing headquarters building on May 21st. The hope of the protesters is to shut the building down for the day.
Also, the Adler Planetarium, Field Museum and Shedd Aquarium will all be closed on Sunday, May 20th. Management for all 3 of the museums have also considered closing Saturday and Monday as well.
