Can you name a good place for an Orthodox Christian to retire, either in the U.S. or in another country?

I am an Eastern Orthodox Christian, so the ideal area would be somewhere Orthodox worship is easy to locate

I am considering retiring in or outside the U.S.

Looking for a place where my money goes far; a simple life where my contribution to the local economy will have a good impact on the local population

I wouldn't rule out moving to a place that is economically challenged

I am a retired Vietnam Veteran in my mid-fifties

I have a TAX FREE pension of about $3,000.00 a month

COLA increases yearly and "no off-set" Social Security coming in 7 years to increase my income.

Also, the U.S. VA will pay for most health care claims I submit from outside US.

Some ideas: Romania, Bulgaria and Eastern Europe in general.

Also Southeast Asia and Latin America.

Not worried about culture shock.

My avocation is singing and songwriting.

I'm a retired Registered Nurse, not looking to do nursing, but having a lot of knowledge to share as volunteer.

Thank you for serious, informed answers.
