Never hunted quail really close to leavenworth but I can tell you that the areas between Leavenworth and Wenatchee should be good. I usually hunt the areas between Wenatchee and Lake Chelan on Highway 97 only about 40min from the barvarian village. PM me and I can give you some good locations around there. I know there has to be some once you get down towards pashastan and out of the high country, just havent had experience with them.
