any areas to shoot clay?

[Seattle206]

i was at a friends grandparents house cleaning out the celler and we found a single shot clay shooter and some old clay. drove to the park and launched a couple clays and it worked fine.

are there woods or fields 'close' to the seattle area that are firearm friendly where i can shoot these clays without getting into trouble with law enforcement? last i heard was some place in northbend where my uncle use to shoot his guns freely, but that was 20 years ago.

thanks!
