Every year starting in 2005, chicago-sf.org has hosted a party at Windycon, held on the Saturday night of the convention.
Our first party, in 2005, was Firefly/Serenity themed and titled "Inara's Shuttle." It was organized mainly by Pam Callaway and Lori Reeder. We decorated it with Chinese lanterns and served a tasty punch that Lori mixed up called "Leaky Brainpan." We served Chinese candy and various other snacks. Many members dressed up as characters from the show.
Our second party, in 2006, was Doctor Who themed. The primary organizers were Pam Callaway and Nina Marie. We constructed a TARDIS console in the party room, and made a TARDIS door outside the room to create the illusion of being inside the TARDIS. We served "Sonic Screwdrivers," "Dalek fuel," and jell-o shots. We also showed some Doctor Who episodes during the party.
In 2007 our party was Battlestar Galactica themed. It was organized by Jynell Greenfield with Rob Han and Jason M. Robertson assisting. The decorations included a papier mache Cylon raider.
Our 2008 party was Buffy themed as "Spike's Crypt." It was organized by Karen Benson with assistance from Lori Reeder, Leane Verhulst and Laura Dombrowski. We decked the party room out with lots of spooky decorations. Our drinks were "Vampire Blood" and "Slayer Blood." We won awards for "Best Overall Party" and "Best Non-Military Decorations." (The theme of Windycon 2008 was military SF.)
Our 2009 party was titled "Shell Beach," based on the film "Dark City." Lori Reeder was the lead organizer for this party. The decorations included a "Welcome to Shell Beach" banner, and brick wall coverings, and spirals. Our drinks included "Mind Eraser," "Teenage Rebellion," and "A Happy Childhood," as well as jell-o shots. We also won the award for Best Party this year.
The theme for the 2010 party has not been decided yet.
