Depends on how far you wanna drive. NE part of the state has LOTS of grouse (read: Stevens Co, Ferry Co) but that's a ways. We go up to Skykomish area just west of Stevens Pass on Hwy 2 and check out clear cuts off of Forest Service roads, but it's hit and miss. Tried to get out last year and try up north near Rockport and Sauk River area, but dogs got into not one, but TWO yellow jacket ground hives (40 miles apart) and were covered in pissed off hornets! We never saw any grouse and headed for home after the second encounter, but I hear that's still a good area. Good luck - just getting out with the dog looking for 'em is fun!
