I've been to American Samoa once and I absolutely loved the culture there. The people were very proud of their heritage and let me know it. However, the one thing that I loved most about them was their sense of humanity. They are some of the most charitable and caring people you could ever meet.
This looks like such a fun adventure! A helicopter ride would be fun no matter what, but in such a beautiful, tropical area, I'm sure it would be breathtaking. The beach itself is gorgeous, I love the white sand.
