One last bit of info for you to understand that our desire to live there has little to do with money. We recently adopted a creole baby girl.
For the record, and a bit off topic...
One of my cousins and his white spouse adopted one black kid and later found out that the mother had another and wanted to get rid of it. They took his brother as well. I fully respect them and you for taking on the responsibilities of another's offspring and loving them as your own. Add to that the fact that you knew, understood and accepted any difficulties in raising a bi-racial family, you are to be commended.
Incientally, my cousin moved to Paupa New Guinea though not for racial reaons... they are missionaries.
My wife and I had considered adopting and we've even briefly looked into adopting in Belize. It appears it's not really an option at the moment for so many frustrating reasons.
