I sometimes wonder this too but people are different. I'm originally from Seattle and spent about 38 years there. We left for a lot of reasons but mostly the sky high real estate and the lack of sun. The weather is so heinous and gray most of the year that I became suicidal

I prefer higher heat in general. But, Washington has a lot going for it in terms of nature, educated population, fewer republicans, that sort of thing. I'll never move back but I enjoy visiting my family. I'm always ready to leave though
