There's going to be a Wikimedia/Wikipedia booth in the exhibition hall at the Southern California Linux Expo, coming up on February 12-13, 2005 at the Los Angeles Convention Center.
More information on the expo in general: http://socallinuxexpo.com/
We'll have a computer set up for visitors to marvel at Wikipedia, and perhaps trundle out some fliers or a few CD-Rs of goodies. If you'd like to help out manning the booth, *please* sign yourself up here:

and drop me an e-mail. So far there's only one other guy listed and I have no contact information for him.
