I been chasing these damn "Phantoms" for years, if you value your sanity, do what everyone has been telling you, head east !!
If you have already lost your sanity, and want to really challenge yourself, get out in the woods NOW and start looking.
There are birds scattered around from Capital Forest, north to Mason County, and south on both sides of I-5 to Vancouver, I have seen them all the way out by Palix (coast)
The hard part is finding them, then being able to find them again...

I do not know where they go, I think they rendezvous with Sasquatch in the spring...
But, put a little boot leather on the ground, and you might find some tracks, droppings, feathers, etc.
It seems I only get to hear them Gobble in March, right at daybreak (if your still in your vehicle, you missed it) so your best bet is to get a COMFORTABLE chair, and after going through a pair of boots, hopefully locating some sign...
If after miles of searching, you do find some sign, get a spot high on a ridge, settle in an hour before daylight and watch the sunrise, and hunt coyotes.
(DO NOT USE TURKEY CALLS UNTIL SEASON)
If you are in a good spot, you might hear one accidentally reveal his position, but don't count on it...
Once you do find a few Turkeys, TELL NO-ONE !!! or you will have company !! (probably will anyways, but oh, well...)
These birds rarely come out in the open, don't expect them to be in any fields, the live in the woods.
During season, turkey calls will bring in coyotes, one reason IMHO they are so quiet, the noisy ones get eaten !!
If you get in a good spot, make a few calls, and only a few calls, then sit still until your butt goes numb...
Then sit there some more...
when you finally decide that you are in a wrong spot, and get up, do not be surprised if one is standing right there in front of you, seemingly from out of no-where
