There is a Facebook group for KoW players in the Washington area that is active. I personally don't use Facebook as I prefer boards like Ordo. Most FLGS in my area are MTG heavy, even though I did check out Blind Dragon Hobbies (in Kent) per @TheBeninator suggestion and they do have all open wargaming (WFB, T9A, 40K, KoW, etc.) on Sundays.
