Hi Carl
A very good point.
Fortunately, at the Grand Canyon it is unnecessary photographically to get close to the edge.

That is an opinion not shared by all.
I live in Arizona, been to the Grand Canyon more times than I can count over the years, and I have never seen the need to get close to the edge in oder to get an image. But, I see people acting recklessly in close proximity to the edge
every time I visit! Admittedly, they do wind up with views that I'll never see.
