In the spring, you can basically get 3 birds (2 birds eastside and 1 bird westside; note - Klickitat is considered eastside for turkey hunting purposes).
In the early fall season, no matter what happens in the spring, you can still get the 3 birds mentioned above.
Then in late fall (from Nov 20th thru Dec 15th), you have been allowed to take 1 additional bird of either sex in units 105 thru 124, no matter what you did in the spring or early fall.
That's 7 birds you have the chance at each year ... not saying that I agree with the current expanded harvest, but that is what the state allows.
Good luck ...
