Depending on how often you want to do it, you could hunt out of a tree stand. Bears right now are keying in on berries, so if you found a berry patch you could get in a good location and get a bow shot. I haven't hunted around seattle lately, but I did two years ago and used this approach. I shot one from 20 or 30 yards after a few evenings of hunting. I did it with a rifle, but if I would have had a bow I easily could have gotten a shot. The bears will use the same locations every day, and if you find a good location there can be a lot of bears using a small area.
