WA is Hard to find good public hunting. Alot of the area's the Elk and Big deer are in are private property. Unless you know somone local that is knowlegable of the area you want to hunt, you may need to hire a guide that can get you into the Elk and Deer Hot Spot's! Good hunting spot's in WA are on the DL "Down Low" . But good luck anyhow. WA has some good hunting
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
