Not taking away from the amazing group of people here on the Zoo Forums but we have a good group of about 300 or so people on Facebook for Chicago. It is a group that was formed for the IE Tour and now have shifted over to The Joshua Tree Tour. I have just become the new admin of the group and we plan pre and post show get togethers, have great discussions, help each other, and all that fun stuff. If interested here is the link to join.
