Wow this was a great read!
This post took me on a trip down memory lane...
I was raised in the Virgin Islands on the small island of St. Thomas. We have iguanas & wild chickens everywhere! We actually call them "Yard Bird".
If you are still traveling through the Caribbean, I suggest you check out the US Virgin islands. You won't regret the laid back lifestyle, the local culture, and the friendly people!
Plus the water is always a warm 20 degrees C.

Cheers!
