If it is still around, the Elma field is probably closest to you. If you don't mind driving a bit, and all of the fields are open on the weekends, some good woodsball includes these fields:
Paintball Inc on Ft. Lewis
Operation Paintball in Graham
KC Crusaders in South Prairie
Nothwest Paintball Park in Bremerton
I recommend the last one as they specifically cater to newbies and women. You won't find any tourney guys there deciding to head out with walk-on's, just to get some easy scores and feel better about themselves.
