He obviously has no fear of heights!  It was an amazing thing to watch.  He hopped over the railing as if there was a solid floor on the other side, walked across the beam, and stood for what seemed a very long time (since I was holding my breath) waving his arms and directing the group of people posing for the photo.  He took several shots, and then walked back across the beam and hopped over the rail again.  Nothing to it - a shot of the wedding party and all the guests!  All in a day's work!
