I heard the guys that did some recent digging actually started to make things better down there but the locals had a cry about other people being down there getting all territorial.
And with regards to the bin. If other people cant put rubbish in it, why is it there? And if people don't like it overflowing, the person responsible for it should empty it before the rangers, walkers and horse riders complain. If the person who put it there isn't going to empty it, either un lock it so someone can, or get rid of it.
