I encourage everyone in the Seattle area to constantly remind everyone of how much it rains. Hopefully it will slightly cut down on the number of Californians moving to the PNW.
As a long time Seattle resident the only way to make it through winter without becoming depressed is to take up skiing, kiteboarding or some other sport that is fun and gets you outside in winter. Additionally, a two week vacation to Hawaii or another sunny location is also a must. Otherwise SAD will start to ruin you by the time March rolls around. Last year was brutal as we only had 11 clear days between October and May.
i live on the other side of the mountains, its usually nice an sunny over here for most of winter, but much colder. We also have much hotter summers and forest fires in the late summer, but hey, no grey gloom.
