Capitol Forest or Skookumchuck area would be the closest to Oly. However be prepared to burn a lot of time and shoe leather just to find sign or birds. Easterns account for less than 1% of the state harvest and you can take just 1 and only in the spring season. I would suggest NE corner of the state such as Stevens County (ie - Colville/ Kettle Falls/ Chewelah/ Rice/ Hunters/ Springdale), Ferry County, or Pend Oreille where historically 2/3 to 3/4 of the state harvest happens.
