HEY CHICAGO - Event Calendar That Shows What is Going On In Chicago

I stumbled across a great website that has a calendar and shows basically everything that is happening in the great city of Chicago and the surrounding area.  The site is called HEYCHICAGO and here is the direct link to the events calendar.

You can signup to have event notices sent to your email and you can also post events for free. It's a great site if you are living here and looking for something to do or if you are planning on vacationing in the Windy City.
