We have been approached by LFL to help with an event in Denver on Sept. 10th at the re-release of THX1138. It seems that they want Imperials and Rebels to hand out some trinkets or other stuff.

We're planning to have some cool giveaways that we'd like the 501st and/or Fan Force groups to hand out, with attendant PR. Further details will follow. /quote

It looks like there are a number of cities. Hopefully, they've been contacted as well. If not, go anyway! Feel free to contact me for information!
