I dont live in the area, but i assume there must be some game shops nearby?
In my area, one of the stores has organized crossfire play, and the other has two separate groups that play weekly, me being one of them. You can also try meetup.com That is were i got some steady players for my games. Even if the stores don't have anything going, you could start something yourself! Its only a $60 investment, and i haven't regretted mine for a second. Seattle is an awfully big place, so it shouldn't be to hard to advertize at the game store or on meet up to find three more like mind gamers
Good luck!
