So in my group we going we a theme of "Free Seattle." Anyone know any good source material I can look up to get some info on this?

There was some discussion of a Seattle Independence movement way back in the original Seattle Sourcebook. I don't remember if New Seattle or Shadows of North America had much to say about it. The theme actually seems to be disappearing as the product line has progressed. If you want to do it you'll probably have to mostly wing it.
