If you haven't already visited you definitely should! I never had the chance to live there but did spend a couple of weeks visiting and it was awesome. Reykjavik, driving the ring road, all those cliffs, waterfalls, national parks, it's all great. That was before this Lemmy bar existed otherwise I would've visited that too.
I've too wondered how feasible it would be to relocate and/or retire to Iceland but that seems pretty far off from reality.
Don't worry, after we invade and occupy purchase Greenland Red, White, And Blueland, I'm sure we'll "purchase" Iceland, too. Then we can all go live there...
Sadly, as I'm not from the US, it would not really help me (in fact, make it harder). Funnily enough, Iceland was actually occupied by the US during World War II - which they did pre-emptively, worrying the Nazis may pull off another stunt like with Norway and endanger shipping from there if they don't.
