Someone needs to point this out, just in the sense of full disclosure.
First, the people in the Pacific Northwest (which I absolutely love) are in the habit of exaggerating the amount of rain they get, simply to discourage others from coming out there and clogging their roads and raising their cost of living. Be aware of this, and discount all their moaning and groaning about the weather by at least 40%. Sure, they get a lot of rainy days, but it does NOT rain all day on those "rainy days." Only for a while. Sometimes only for a very short while.
Second, it's all about your perspective. The first time I went out there, I was visiting friends, and I commented on the rain. They immediately corrected me, saying "No, you shouldn't talk about the rain; rather, you should notice how green everything is."
