When we were in Labadee, Haiti this past July, we discovered this fun thing to do. You start out 2400 ft above the beach, get strapped into a sling, and slide down a zip line at speeds around 50 mph to the beach below. Traveling down over the water, and breaking waves, can only be an incredible experience. We watched from the beach, but now that I have seen this video, I would like to give it a try, if and when we go again. This excursion in Labadee is called the Dragon's Breath Flight Line,the longest flight line in the world over water.
