We're been nomads, lived in NH, SC, NC, MI, CT, NY, VA, FL, TX, HI, CA, Japan, Korea, and the Philippines.
Can't complain about NH, lots of hills and lakes, generally people with a good work ethic, low crime, access to the history and culture of Boston, etc.
The Pacific Northwest, Idaho and Wyoming are appealing.
I love Alaska in the spring, summer and fall. I've thought about buying land in Two Rivers, and being migratory - maybe Hawaii or Panama for the winters.
Spent some time on Guam a few years ago, I could do that for a while. Odd ecology - great diving, no birds.
Outside the US, I like the Galway coast of Ireland, and we've recently been discussing New Zealand as an eventual retirement location. Capetown, South Africa is probably the most beautiful place on earth, too bad about their political nightmare.
