Yes, we've thought of South America as well, along with a hundred other places, but so far none have been compelling enough to drag us out of here.
And the Bay area is hard to beat, with its mix of gorgeous scenery, lovely (mostly) weather, great (mostly) people, and pretty much everything under the sun available relatively nearby.
Pensacola is gorgeous as well, but if I went back to Florida, it would be to somewhere far less populated. And, frankly, anywhere in Florida is vulnerable to sea level rise.
Thanks for your response, and have a lovely weekend!
