The Azores are one of the neatest places I've ever been. I could live there. Just loved the beauty and the culture. It had a vibe I could get used to. Not many people either, which is a big part of why it is special. Definitely hope to go back again someday and spend much, much, more time.
I can see the wisdom in an Atlantic Circle without hitting Europe, unless you wanted to wander up to Scotland or something.
