Because of the isolation of the track and the distance from the residential areas, I find it difficult to believe that people walk here and bring their dogs on a lead.  But what are the tied up plastic bags on the fence if they are not collections of doggy poop.  Any ideas?  They cannot be lunchbags used by Technopark staff because they are on the outside of Technopark’s most outside fence.  Strange. Colourful.  Unnecessary additional reminders of man’s encroachment on natural areas.
