I been in seattle for last 15 years. I love it, the weather is nice. A lot of outdoor activities to do. Eastern WA is great for hunting, camp trips etc. If you love skiing etc, this is the place to be. All sorts of activities to do.
If you do fly, the air space is not so bad. When you're near Sea-Tac air port area you can't go above 2k, and fly by Sea-Tac is breath taking. It's fun to see air craft landing below ya and those in the pattern above ya.
