In this world where everything has to be dummy proofed I found a surprise when I visited Horseshoe Bend outside of Page, Arizona. There was no guardrail, fence, or any protective barrier around the canyon wall! You literally just take one step too many and it is a thousand foot fall. This is great for photography though, step up with the wide angle lens and no fencing to get in the way. Just a nice drop off. I got the goose willies just putting my tripod leg an inch from the drop off. How did other people handle it? Well, not good in my opinion.
