The cliff at Peter Skene Ogden State Park,
Terrebonne, Oregon credit 
A small park along Highway 97 in Central Oregon reminds me why we have railings and warning signs.
One can barely escape the dramatic scenery of the high desert with rock of unexpected shape always on the horizon. But in this tourist's turnout the shear cliff is only a couple feet away, maybe less.
Someone thought to build a stone wall three feet high to discourage transgressing those last few feet. Were there deaths? Daring rescues? I can only guess. But the oldish wall is much younger than the cliff.
Much later, maybe within a decade, the wall was augmented by a large sign that said, do not cross wall. Apparently the single foot of ledge on the far side was too inviting for those seeking the best view. Maybe only one?
Freedom
Who decided it was their responsibility to protect me from my own curiosity no matter how foolish?
What network of owners, operators, legislators and litigators cooked up these solutions?
When someone makes my welfare their job should I insist on consent? Am I qualified?
If I am qualified, what responsibility do I have to share my knowledge?
