I mean same, but you asked. I work right next to Grant/Millennium/Maggie Daly Park so unless I am on vacation I kind of can't escape it. Do312 is a good site to look at for overall info about what is going on in Chicago on a given day. They send daily emails so maybe don't actually sign up for an event through them, but it's a good site to find out about events if you want a one spot shop for shows, festivals, free city events, etc. I linked "today" as August 1, but feel free to change the date and browse for ideas.
