watched this video a while ago, and returning to say that since then I have ridden on one of these in germany while visiting the bastei rock formations! the ferry crossed the elbe river and it used a wire that ran mostly underwater, not above like the one in the video. it was the only way across at that point (no bridges so it was very necessary and useful!) which I was glad for because I had wanted to take a ride on one since seeing this :) thanks for the great video!
