Where will you retire, assuming you have to decide right now?

I have a hard time imagining where I might go, or even why I would go anywhere else. I might like to travel more, but this is where I live and where all the people who know me the best live. I have no reason to go anywhere else. Perhaps if I had family elsewhere or friends elsewhere, or some kind of retirement activity I really wanted to do. But I have none of those. Everything is here.

Where would you go and why would you go there to retire?
