It's a bluff hike and there are warnings to stay on the trail. But we all know human nature! And it's obvious here that the wear to the edge is well worn.
In all fairness to innocent inexperienced hikers and children, I think the sign should show how an overhang appears to be safe from on ground, but can easily give way.
This is the other end of a hike I take a lot on Ebey's Landing.
