Western Washington is all about the gates.
At least where I hunt.
.
Find a gate that does not connect to another road system, and hike it.
When you get to the end of a spur, or to a decommissioned section, tighten up your laces and get off the road.
.
Follow Creek bottoms, major game trails, etc...
.
Almost every hunter out there will walk roads,few leave them because it's thick and nasty, and no room for a shot...
But once you get 50-100 yards from the road, it opens up.
