Yahoo news just had an article not more than a week or so back about places to retire or move overseas.
Ecuador was mentioned as one of the top spots primarily due to good health care, weather, and a large English speaking expatriate community already living there.
What an adventure for you folks!
Best of luck. So many things I would just love to travel through South America and see. Hope you get the opportunities to do so as your proximity is certainly going to be as in the neighborhood now.
ON EDIT: SHOOT! I actually found the article I mentioned. Here's a link for your reading;
Cuenca, Ecuador # 2 on list place to move overseas.
