If you've never been, Seattle's a great place. We (my family and I) used to live there and I think you'll find it full of opportunities. As far as outdoor activities, if you can think of it, you'll find it within easy drive. If you're into music and you have some extra time, make sure you visit the rock & roll museum.
Just remenber, it rains on average about 260 days a year. If you can live with that, you'll really enjoy Seattle and all it has to offer.
