Fourth: These helicopter pilots are nuts. I like how this guy opened his door to keep the trees in view. This is routine, and you should see the speed at which they maneuver through the trees. I have seen some drop in 20 meter clearings to land (surrounded by tall trees).
Finally, they have some wicked waterfalls. Check out Sutherland Falls, the tallest in the country, dropping a full stream of water even in dry times a staggering 1,904 feet!
(I know, I've got to get my head out of the way for more of these shots...)
