Pheasant: In WA I've only hunted a couple release sites near me. Done really well at Kosmos. Not so well at Scatter Creek. Hunted wild birds in Oregon, South Dakota and California last year. I need to investigate eastern WA more.
Grouse: Never really hunted them, just a couple ruffed grouse (CA) with pistols when opportunity knocked while driving around. Interested in pursuing that venture, but hopefully not terribly far from Lewis county. I've been told there's some rather local west of me, but most indicate east into the Cascades has better prospects.
