Liberty, Taneum, Teanaway, Salmon La Sac, Stampede Pass, Washington Pass, Pryamid Pass, Little Naches, Manastash, Cloversprings, Bethel Ridge, Ellensburg Pass, Wenas, and Oak Creek to just name a few. All within 3 hours of the Seattle area most closer. And hundreds of miles if not thousands of miles of open roads (when snow free). Firewood gathering, mushroom (edible) hunting, berry picking, antler hunting, game hunting, mine exploring, what have you as there is a place for it. Go for it. Get out there and hunt, fish, camp just do it. Forget the naysayseers that say everything is locked up and gated. They are wrong.
Just pay attention to the gates you do find. If a Forest Pass is required please have one. Please pick up after your self. Drive the forest roads safely. Wave and be friendly to the other forest users.
If you plan to go shooting. Be sure of your backdrop and range area. Don't put a bottle on top of a stump. Don't use the forest as a backdrop. Use common sense.
Keep the use of ORV's to approved areas. The Forest Service has maps of such areas.
All is good!
