I am sure i know the place in your pics. My wife and i walked through it , the other year and on turning a bend were confronted by a guy doing his business at the side of the track!!! and not a no 1 ,i might add.This kind of thing ruins it for us all.Ah but, you don't stay for six months in one place.
There is a certain odour in the place I photo'd, easily discerned if you just cycle through on the track.
Cheers Cris.
PS, if not where i am thinking ,it looks the same but the comment still applies.
