Where would be a preferred state to live in?
That's a difficult question, as it's so tailored to each person. Some folks value cheap cost of living more than anything else. My parents are like that, and so they always thought about, if they had to move, going somewhere like Arkansas or Mississippi.
Of course, warm weather figures into it as well, that's why so many like Florida and Arizona (and because they can live bunched up with a similar demographic, if they choose to).
For us, we both have conditions for a "dream" state to move to, and they're sometimes at odds. We both want East Coast, near an airport that can get us to Europe (excepting Atlanta, I hate that airport).
MrsT is more concerned about warm weather and a dedicated 55+ gated community, I'd much rather have four seasons and an urban location with a good mix of ages of residents. Right now, we're thinking that North Carolina, inland from the coast, might be a workable compromise.
