Shorthair if I remember correctly you are in E-Burg.
The hills and draws all around you are full of quail. Lower Colockum (sage hills, flats, brushy draws) and Quilomene (same as Colockum). Umtanum try crossing the foot bridge, and pretty much anywhere else along the river from Cle Elum down south are all spots that hold birds.
If you know any ranchers that have sage and water on their land get permission cause they'll also have quail.
