The pic above shows WooZah looking toward Fiveways Crossing whereas Montana is stood next to a new addition to the landscape. The stone cairn must have taken some constructing, and its covering a couple of plastic bags, a sandwich wrapper and two 2 litre empty pop bottles. Presumably whoever it was that left this mess carried the contents of the packaging up the hill for a picnic, but felt incapable of carrying the lighter empties back. The energy expended trying to bury the offending articles must have been more than carrying it away to be disposed of.
Or perhaps they thought it was a time capsule, in a thousand years a keen amateur archaeologist will uncover the secrets of their prawn wholemeal and thousand island dressing, or maybe its an offering to the small gods of Bonsai Mountain, or a signal to a alien race who scour the universe for discarded packaging, or maybe they were just lazy gits who deserve a kick in the farmers. (Somewhere that gives them two little acres)
