Buy a map of the MT. Baker Snoqulamie National Forest; you can hunt National Forests, but not National Parks or State Parks.
Dept. Of Natural Resourses lands are huntable too, but very poorly marked; contact the DNR website for maps to buy.
Gated off logging roads or abandoned slash roads are good places to walk and hunt.
With snow season upon us, good luck driving into the National Forests to hunt...They don't plow the roads!
