Where is info on travel party/group heading to Chicago?

I'm sure I'm not the only one spending Columbus day weekend in Chi-town. Is there another group/party etc to 'take over' Chicago? I'd like to be around fellow fans, where is the group? Where is the post?

As for the game, I'm also looking for tix, any insights on tix? Does Astros reserve any away game tix for fans? first time following them during post-season. It'll be a Sunday game in Chi town right? hoping for a sweep and we can see the W in Chicago.

General recommendation/tips appreciated for traveling fans! Looking forward to a fun weekend!
