Tastes are subjective.
If I could afford anywhere, Palm Spring wouldn't be on my list.
Huntington, Birmingham, and Montgomery AL offer some cultural amenities.
Gary IN is F list, not D list.
I'm aware of the Hindu thing of old people letting go of material things to become spiritual wanderers. If they want.
As stated before, for me personally repatriating to any place in the US is a third choice after staying in Thailand or moving to a third country like Mexico.
But I'm sure many others on a budget put retiring in the US as the most desirable.
