Two part answer:
1. I despise the weather (overcast and rainy most, most, most of the time) but I would not be happier in a colder place, even if it meant warmer summers. I do very well in tropical climates. Hot and humid, with me close to a body of water. That's the way I like it.
2. Apart from that one very huge factor, I love where I live. We are 25 minutes from town in a very small (few hundred people) community at the end of a peninsula. It is quiet here, the street holed and worn, and houses tucked into the forest. I know my neighbors and enjoy them, though they are not close friends. We trade fish for shellfish, yard work for fence work, money for car repair, and favors. Our street dead ends a few hundred yards past our yard so there are only a handful of cars that pass each day, thus our young children and dog are outside much of the day, and without worry.
It is a mile from the Sound, which is a most wondrous and unique ecosystem. The water is cold but unpolluted and we are able to catch crabs and starfish, to pet sea urchins, to watch the harbor seals nurse their young year after year. At night I'll park by the docks and sit on the bulkhead, listening to the boats rock in the water, their gear singing quietly. Because it's rainy and grey, our forests are glorious, carpeted in ferns and moss, sparkling green. It's quite magical, I think.
Too, the school system is great and town (a small city characterized by it's state capitol status and the liberal arts college) is not too far off. Likewise, Seattle is close enough to drive to for a day trip, as is the airport and museums. Tacoma is even closer and Portland within close distance. Most importantly, my community is here. My mother lives in town, and my girlfriends who are my chosen family are also within close distance, as are their children who are close with my own children.
So, no, I wouldn't choose to live somewhere else. BUT if I could transport my town to a tropical island? You bet I would do it :-)
