I enjoy reading those things when I am out and about on some forests, as many do have these posted in the bathrooms. In our regional office and some other forests you never see or hear of them.
It is like most places, someone finds and latches on to a good idea, but not all know about them. Thanks for sharing this idea of getting the information out.
Side thought: Most of these I have seen are posted in Idaho. I wonder if Idahoans have been sufficiently taught to properly aim while reading? Sorry, I just had to add that.
