I took this picture in Albuquerque, New Mexico, while riding on the Sandia Peak Tramway, a cable gondola ride that is supposedly one of the longest in the world. Anyway, half way up I saw the other gondola coming down, and there was a guy standing on the roof. I hurriedly took a picture. When I asked about that, I was told that's how the maintenance workers get from one end of the cable to the other. Click on the image to see a larger version.
