Our house on Maui (left) got a retaining wall. This is the start of the project, where all you have are rocks (December 2006).

The walls on Maui (and I think many other islands) were built by people from Tonga. They seemed to be the only ones in the business.

Our neighbor's house (right) already has a retaining wall.

(Oh yes, our, and our neighbor's fences are in the picture, too. Our "lanai" is above the garage. We spent many hours there watching the beautiful scenery, and the shipping in the harbor.)
