What county in Washington prohibits discharging firearms? There is legal hunting in every county. IIRC you are in King County. Not counting rush hour(s) very few King County residents live more than a 45 minute drive away from one or more outdoor gun ranges. The large timber companies demanding you purchase one of their use permits before driving onto their property put a damper on a lot of the traditional plinking but there are still the national forests. I'm not sure if Warehouser has changed their policies but they used to be O.K. with plinking and might still be if you bought their use permit.
