We came across a few of these signs on our walk. There were quite a few poo bags lying under there not sure if the person that made the sign dumped them there or other people did to wind them up some more. I do see her point mean if your going to put it in a bag why then leave it there. The annoying thing about where we walk is that even though its a very large area there are only poo bins at the car park? I guess people don't want to walk around for an hour carrying it. Bless her she would have a heart attack if she went to cobham common there is just poo everywhere all along the sides of the paths that people don't even bother putting in bags.
