And that guy whose wife is Colombian? Try living there for a few years and, if you survive, come back and tell us how it is.
Seems you didn't make any research before you made that statement, the number of American expats in Colombia (and many other places in South America for that matter) had exploded in the past decade. Go figure! I have a few friends that are real state agents there, the vast majority of expats purchasing properties in Colombia are from the US now a days!
