I was there in November. When I went to that spot to take my shot, my wife grabbed me around my neck, yanked me back and asked me if I was crazy. I haven't answered her yet.
That is great!
I spent two hours perched right at the edge with my camera on short mini- tripod to get the sun setting behind the scene. It was worth it. I actually had to squeeze in between a bunch of other people including lots of tripods to get a clear shot. It was unbelievable how many people were there. My wife who is usually afraid of nothing, wouldn't go anywhere near the edge. It was a real role reversal for us. She told me later there were TWO weddings going on simultaneously at the cliff's edge at sundown. I didn't notice as I was honed in on getting the shot.
The guy next to me (he let me squeeze in next to him) was smart. He was a NY studio pro. He had his camera on a tripod right at the edge of the dropoff but he was behind it a foot or two controlling it with his iPad. HE told me that way he didn't have to be right at the edge! He had a 5DIV like mine and showed me while we were waiting for the sunset how to set it up for that remote control. I tried it when I got home and it worked. He said he shoots that way in the studio all the time, touching the area for focus point just like on the screen in live view but on the iPad instead. I learned something really cool while waiting for that shot!
